Zhengzhou Zhongnan Jiete Superhard Material Co., Ltd. Zhang Xiangfa
I was a master student of Professor Wang Guangzu at the end of the 1980s. I was fortunate to receive the guidance and teaching of Professor Wang Guangzu. Mr. Wang's focus on super-hard materials, dedication, quick thinking, meticulousness, and hardships... and many other generations of intellectuals have benefited me a lot. In many years of work practice, he started from the development of China's first diamond, to the intermediate test and industrial production of diamonds, and worked hard in the superhard materials industry for more than 50 years. He witnessed and witnessed China's superhard materials industry from nowhere. The development process from small to large, from weak to strong has made outstanding contributions to the industry.
First, the passion to join the diamond
Mr. Wang graduated from the Chemistry Department of Wuhan University in 1956 and was assigned to the Beijing Institute of Machinery Industry Tool Science Research Institute. In 1957-1959, he was sent to the Soviet Chelyabinsk Grinding Wheel Factory and Chapolos Grinding Wheel Factory to learn the production technology of electric corundum smelting and its processing. After returning to China, he was sent to the Institute of Abrasives Grinding in the Ministry of Machinery Industry. (referred to as Sanmao) work in the abrasive research room. At the time of the establishment of the synthetic diamond development project urgently needed by the country, Sanmao was in the preparatory period, and there were only a handful of highly educated engineers and technicians. Wang Guangzu was assigned to the 121 research group and engaged in the research and development of synthetic diamonds. China's first synthetic diamond, participated in the development of China's first six-sided top press, intermediate test of artificial diamond and industrial production. It’s a lifetime.
Synthetic diamond is a high-tech developed in the 1950s. At that time, only the industrialized countries such as the United States, Sweden, Britain, the Soviet Union and Japan were in control, and the technical blockade was imposed on China. However, China’s natural diamond resources are scarce. All departments of the national economy, especially precision machinery processing, oil exploration, geological exploration and electronics industry, are in urgent need of importing from the Soviet Union and the Congo every year. In 1960, the international situation changed suddenly, and the source of diamonds was severed, which seriously affected the process of socialist construction in China. Therefore, the artificial method of manufacturing diamonds became an important issue that China urgently needed to solve. To this end, the state has developed its research as a key project 121, and in October 1960 issued a scientific research task for the development of synthetic diamond. The Joint Research Group of the General Machinery Research Institute of the First Ministry of Machinery Industry, Sanma Institute and the Geological Science Research Institute of the Ministry of Geology, including: Yu Hongchang, Wang Guangzu, Hu Enliang, Xu Jinfeng, Yao Yucheng, Zhou Jitang, Sun Rongchuan, Xiong Wensong, Lu Feixiong Yu Zhengmin, Li Jinbao, Du Fuchang, Zhang Yonghua Jin Qiuye, Liu Kaizhong. Under the guidance of the unprepared and unpredictable, Wang Guangzu and Yu Hongchang and Zhou Jitang extensively collected, collated and analyzed relevant foreign technical materials, and wrote the "Basic Synthetic Diamond Technology". The book (internal control data), and based on this, provided the first experimental program, established its own graphite-diamond balance curve, as the main basis for the selection of thermodynamic conditions of the synthesis process, and made a careful and meticulous implementation of the technical solution. arrangement.
After more than two years of cooperation in the research team, on the evening of December 6, 1963, on the domestic 300-ton type 61 double-sided anvil ultra-high pressure high-temperature device, high-purity graphite powder was used as raw material, and nickel-chromium alloy was used as catalyst. The first synthetic diamond in China was successfully synthesized under the pressure of 7.8 GPa and high temperature of 1375-1550C. Recalling the scene at the time, Professor Wang still remembers: The 32nd synthetic stick is opened, and the beautiful secret light shines. The people present can't believe it. This is the first synthetic diamond in China?! According to the X-ray diffraction analysis of the authoritative department, the spectral line is completely consistent with the natural diamond. All the members who participated in the experiment cheered for it and jumped for it. Successful! It was a memorable night and a night worthy of pride. It will serve as the beginning of China's synthetic diamond business and will last forever.
The birth of the first synthetic diamond in the land of China has become the sixth country in the world to master diamond synthesis technology. Whether it is the development of China's high-pressure high-temperature technology or the discipline of crystal growth, it is a milestone. This is very remarkable for China, which has a weak industrial base, poor economic strength, and a backward science and technology. It is able to achieve technological achievements with world-class levels. To this end, he won the 1978 National Science Conference Award.
Second, the achievements in the superhard field are remarkable
The successful development of the first synthetic diamond is only the first step in the industrialization of diamonds. In order to turn to industrial production as soon as possible, in April 1965, the Ministry of Machinery and Industry officially issued the approval document of the National Science and Technology Commission "Improved Diamond Intermediate Test Plan Task Book", clearly requiring the establishment of an intermediate test base in the three abrasives, stable synthesis process and improvement before and after Processes to achieve industrial production levels.
In cooperation with the Institute of Foundry and Forging Machinery, Sanmao began to design the DS-023A hinged six-sided anvil press with Chinese characteristics in 1964. In order to grab the speed, the principle of trial design was adopted. In 1965, 8 The monthly manufacturing installation was completed, and the first 6×6MN DS-023A press was born in China. Mr. Wang was the team leader of the process test. The members were Shao Dehou, Yu Zhichao, Kong Lingchun, Li Jinbao, Yan Juwu, etc. In the synthetic process test, the first encountered the problem of high pressure sealing. If this problem is not solved in time, the process test will be It is impossible to proceed normally. Through the observation, thinking and practice of several days, days and nights, I finally found the problem that the angle between the inclined faces of the two adjacent abutments was not suitable. A major breakthrough in high-pressure sealing technology has laid a solid technical foundation for its application in industrial production. To this end, it won the 1978 Henan Provincial Science Conference Award.
In order to raise the artificial diamond crystal growth technology to a new level, from 1966 to 1969, Mr. Wang undertook a research project with a technically difficult part—single crystal large particle synthetic diamond. The following results were obtained through experiments:
1. Obtaining a single crystal diamond of 1.0-1.5 mm which is preferably in a crystal form;
2. The success rate of synthesis on the single-pressure source six-sided anvil ultra-high pressure high-temperature device is 70%-80%, while the hinged six-sided anvil press is only 30%-40%, indicating the synchronization of the ultra-high pressure high-temperature device. The neutralization and pressure holding performance has an important influence on the stability and repeatability of the synthesis process;
3. If you want to grow gem-quality diamonds, the seeding method should be preferred;
According to the small volume of the high-pressure chamber, the temperature is difficult to control, resulting in low yield, unstable quality, high cost and economic benefits, in the late 1960s, the researchers of Sanmao Institute first proposed the hinged six-sided In the report of the "man-made diamond large single crystal research device" declared by the Ministry of Machinery, the idea of ​​designing and manufacturing a 6×25 MN hinged six-sided anvil press was proposed. Under the influence of the trend of the world's advanced technology at the time, Vice Minister Shen Hong of the Ministry of Machinery asked us to change 6×25MN to 6×50MN. The press was jointly designed by the Research Institute of Casting and Forging Machinery and Sanmao. It was manufactured by Beijing No. 2 General Machinery Factory. It was installed in Sanmao in 1974. The mechanical test shows that the design specifications basically meet the requirements. This attempt failed because the quality of the large diameter carbide anvil failed to meet the requirements for use. Although this attempt suffered setbacks, it blew the horn of marching into the large-scale press, indicating the direction of the large-scale press, which is undoubtedly the foundation stone.
In 1971, Mr. Wang collaborated with Xu Jianwen on the basis of years of practice and wrote a paper entitled “Study on the relationship between growth of synthetic diamond crystals and pressure and temperatureâ€. The relationship between diamond production, quality and pressure, and temperature is described in the paper. The laws and principles of the heating process have always guided production. According to the observed phenomenon, the critical radius rk on the relationship between the grain radius and the free energy in the system is shifted by one position. The result has caused a great academic debate. After the debate appeared, the editorial department of "Chinese Science" sent the paper. To the famous scientist Wang Daju in China, Qian Xuesen, the two old gentlemen said that if the mathematical derivation of the author's curve is correct, then how to define the rk author can completely explain according to its actual observations. Allowed, because the position of rk in the classical theory is obtained under the specific conditions of normal pressure and normal temperature, and the authors of the paper are observed under the conditions of ultra-high pressure and high temperature. The conditions of the two are very different, so rk moves a position. It is the development of traditional theory. In order to verify whether the calculation results are correct, Professor Wu Renren, a mathematician of Zhengzhou University, was invited to conduct an audit. The answer is that the calculation results are completely correct. The papers were published under the approval and support of the above-mentioned well-known professors, and they were published in both Chinese and English. Because it is a creative paper.
At the 1973 National Planning Conference, it was determined that Jilin University and Sanmao were jointly responsible for the systematic theoretical research on the growth of synthetic diamond crystals. In order to clarify this academic problem from the combination of theory and practice, experiments on the relationship between carbon materials (mainly graphite) and diamond crystal growth; experiments on the relationship between catalyst and diamond crystal growth; and carbon and catalyst before and after high pressure and high temperature X-ray diffraction analysis, according to the research results, wrote "Discussion on the mechanism of diamond crystal growth under the participation of catalysts" and "Study on the transformation of amorphous carbon to diamond structure under high pressure and high temperature". The paper clearly states: "Three non-segmentation principle of selecting catalyst" "and the "preferential principle of graphite materials", and the idea that the transformation of amorphous carbon into a diamond structure must go through a graphitization stage. This view has been incorporated into many technical monographs, becoming an axiom, which is a diamond synthesis process. A creative contribution made by technical theory.
In 1974, at the "large particle synthetic diamond" field experience exchange meeting held in Shanghai, on the growth mechanism of synthetic diamond crystals, Mr. Wang proposed that the transformation of amorphous carbon to diamond structure under high pressure and high temperature must pass through the graphitization stage, that is, in carbon. The material material plays a leading role in the structural factors during the diamond transformation process, and provides a practical basis for how to explain the diamond growth mechanism.
From 1978 to 1979, Mr. Wang undertook the key project of the Ministry - the effect of trace elements on diamond performance. The papers based on this were later selected for the 85' Super Hard Abrasive International Conference in the United States.
With the development of China's synthetic diamond industry, Mr. Wang's work is more busy. From 1981 to 1982, he participated in the research and development of high-quality fine-grain synthetic diamond, and won the second prize of scientific and technological achievements of China Nonferrous Metals Corporation. From 1991 to 1994, the research project of the Ministry of Science and Technology of the Ministry of Science and Technology - Microcrystalline cubic boron nitride. In November 1999, he was appointed as an expert of the Technical Advisory Committee of the Zhengzhou National High-tech Industrial Development Zone Management Committee, assisting in the establishment of a super-hard materials and products industrial base, and made an important contribution to Henan becoming a province of super-hard materials production. In 1983, 1986, 1988 and 1989, he won many provincial and ministerial level natural science outstanding paper awards and scientific and technological progress awards.
Third, pay attention to the frontier dedication industry
As a member of the industry, he always pays attention to relevant technology frontiers and industry development.
Promote CBN, he is active
With the reform and opening up in the 1980s, the domestic machinery industry developed. He began to pay attention to the synthesis and application of CBN in China with a keen eye. He selected the CBN raw materials, new catalysts and high pressure synthesis for the selection of my graduate thesis. As it turns out, the topic is very forward-looking. Since then, the climax of a round of CBN research is quietly emerging. Solid basic research has laid a good foundation for my future CBN production and research, which has benefited me for the rest of my life.
He also attaches importance to the exchange and promotion of domestic CBN technology. This is not his own business, nor financial support. Due to his sense of responsibility and mission to the development of China's superhard materials, he has made every effort to create conditions for industry researchers to provide a seminar and exchange. On the platform, he found the support of Wu Zhiying, the director of Zhengzhou Erqi Superhard Materials Factory. Since 1990, he has successively convened Zhengzhou, Chongqing, Lushan and other national CBN technical seminars, Sanmao, Jilin. CBN research institutes such as the University and the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences, and the CBN researchers from Shanghai Silicate Institute, Changsha Mine, Second Grinding Wheel Factory, Sixth Grinding Wheel Factory, Suzhou Grinding Wheel Factory, Shanghai Grinding Wheel Factory, etc. Extensive communication. The climax of CBN research has been set up in China: new catalysts have been used to make progress, and a series of scientific research results have been produced to synthesize high-grade cubic boron nitride of various colors, and gradually transition from laboratory to small batch pilot. With the Lushan CBN seminar as a symbol, China has ended a single, long-term stagnation of cubic boron nitride products, which has brought a new level of research and production of cubic boron nitride.
Today, many years later, China has become a big country in CBN production. We cannot forget the positive promotion of Teacher Wang.
The press is large, he advocated
The large-scale high-pressure chamber is the technical basis for achieving high-yield, high-quality, low-cost production of diamond. It is the key technology in realizing the technical parameters of the “four major†synthetic process of high-grade diamond industrialization.
It has been observed from the synthetic process test of diamond that with the continuous expansion of the high-pressure cavity, not only can the amount of diamond be increased, but more importantly, the quality of the diamond crystal is greatly improved, which provides sufficient for the production of coarse-grained and high-strength diamond. The growth space, in the mid-1960s, sprouted the idea of ​​large-scale high-pressure chamber volume. From 1966 to 1973, a 6×35 MN, 6×50 MN hinged six-face press was designed and manufactured, and the first step of the large-scale press was boldly taken. However, since the manufacturing technology of the large-diameter cemented carbide anvil has not been solved in China, the work of large-scale presses has been stranded.
From the failure of the first large-scale practice, Mr. Wang realized a very important reason, pointing out that without the high-quality carbide anvil, it is impossible to have a high-pressure cavity volume in the actual sense. Large size. The past is, now and in the future, it is still a major high-tech topic for us to fight for. For the first time, the idea of ​​large-scale high-pressure chamber is proposed, and based on this, the fourth five-year plan of China is proposed.
In order to speed up the process of expanding the volume of ultra-high pressure chambers, Xianyang Superhard Material Equipment Group Co., Ltd., Nuclear Industry Corporation 233 Factory, Aerospace Industry Administration 7803 Factory, Shanghai Shenxing Machine Manufacturing Co., Ltd., etc., have successively developed a working cylinder diameter of ф360mm ( 6×10MN) and ф400mm (6×12.5MN) hinged six-face press. For the above-mentioned company to preside over the technical argumentation of the new press design and the technical appraisal before the factory, constructive suggestions were made from the requirements of the synthetic process technology and the problems that occurred during the actual operation.
In order to further expand the volume of ultra-high pressure body in China, under the initiative of Professor Wang, the chief engineer of Hangzhou Gaofa Group, he signed a contract with Xianyang Superhard Materials Equipment (Group) Co., Ltd. in January 1997 and cooperated with Zhuzhou. XKY-6×20MN hinged six-face top press is expected to have a volume of 30~45cm3 in the synthesis chamber, which marks a new step in the large-scale of China's ultra-high pressure and high-temperature press.
Nano diamond, he actively promotes
The challenging 21st century has brought people into a critical historical period. An industrial revolution to save resources and energy and protect the ecological environment is emerging. Just like micron technology in the 1970s, nanotechnology will become the 21st century. Leading technology. Nanomaterials should of course include nanodiamonds that will play an important role.
Nanodiamonds is a very valuable member of the nanomaterial family and its properties are unparalleled in other nanomaterials. In addition to the basic characteristics inherent in diamond, nano-diamonds are, in a nutshell, simple, on the one hand, can be regarded as a "supramolecular", fully exhibiting quantum effects. On the other hand, it can also be Make a very small "macro substance" so that it shows the characteristics of the future.
Professor Wang believes that all of these will bring new challenges and opportunities to the development of superhard materials. In order to promote the further development of nano-diamond detonation synthesis technology in China, to explore its industrialization and expand the application field, Professor Wang and Professor Wu Xijun of Zhejiang University jointly planned and funded by Hangzhou Gaofa Abrasives (Group) Co., Ltd., 1997 7 In Linping, Hangzhou, the Science and Technology Commission of Zhejiang Province and the Association for Science and Technology hosted the “National First Nano-Diamond Development Seminarâ€, inviting the Lanzhou Institute of Chemical Physics, the Institute of Chemical Engineering of Gansu Province, the Second Artillery Engineering College, and the Chinese launch vehicle. Experts and professors from the Institute of Technology, Zhejiang University, Beijing Institute of Technology, Artificial Crystal Research Institute, Sanmao Institute, and Northwest Institute of Nuclear Technology have jointly discussed the industrialization of nanodiamonds and the expansion of application fields.
This is a seminar with high efficiency, high level of knowledge and rich content, representing the latest level of seminars on nanodiamond technology, production and application in China. After the meeting, he edited a collection of "Nanostructure Diamond Development Seminar". Since then, Professor Wang has had a close relationship with the research and development of nano-diamonds. In recent years, the main focus has been on the collection, collation and writing of nano-diamond synthesis technology, characteristics and application of the review or feature articles published in the "abrasives communication" In the publications such as "Industrial Diamonds" and "Superhard Materials Engineering", the use of this new technology to develop the residual heat has made his life in his later years full and meaningful.
In 2002, under the leadership of Professor Wang, Henan United Abrasives Co., Ltd., through investigations in Shenzhen, Beijing and Xi'an, built a nano-diamond production line with an annual output of 1,000 kg, filling the gap in production technology in Henan. .
The 2007 Superfine Diamond Technology Symposium was held in Beidaihe. It is jointly sponsored by State Key Laboratory of Explosion Science and Technology (Beijing Institute of Technology), Beijing Guoruisheng Technology Co., Ltd., Beijing Polystar Technology Co., Ltd., Jingri Kemei Superhard Materials Co., Ltd., and Industrial Diamond Information Network. The conference featured themes including detonation nanodiamond (DND), explosive micron polycrystalline diamond (PCD) and static pressure diamond micropowder (SND). The meeting was hosted by the Lanzhou Institute of Chemical Physics of the Chinese Academy of Sciences, one of the first nano-diamond developers, Professor Xu Kang, and the Beijing University of Technology's nano-diamond doctoral tutor, Professor Shou Shouyi and Professor Sanmao Wang.
He spares no effort in industry work
The Ministry of Machinery Industry revitalized the products in 2000, and issued a key project of "Research on the Product Revitalization Target of the Machinery Industry in 2000" to its affiliated research institutes. This is a predictive topic, which requires the organization of a group of high-level theoretical and practical experience, and the engineering and technical experts familiar with the industry to participate in the implementation. According to the arrangement of the superior, Mr. Wang and others have undertaken the sub-projects of the super-hard materials. analysis. The subject won the first prize of Science and Technology Progress Award of the Ministry of Machinery and Electronics Industry in 1988 and the second prize of National Science and Technology Progress Award in 1989.
In 1993, Shenzhen '93' China Superhard Materials Development Strategy Seminar and Celebration of the 30th Anniversary of Synthetic Diamond Development, Mr. Wang, as the chairman of the editorial committee of the conference, made the theme of “30 years of development of China's superhard materialsâ€. report. The report pointed out that China's super-hard materials industry is entering a period of critical development, the scale is expanding rapidly, the output is rising at a high speed, and the "re-entry" is approaching, facing fierce international competition. Opportunities and challenges coexist at this important moment. Where to go, you need to think hard and make choices! In line with the 30th anniversary of the birth of China's first synthetic diamond, Sanmao hosted the "China Superhard Materials Industry Development Strategy Seminar" based on the initiative of old experts and veteran comrades who are closely concerned about the development of superhard materials industry. Colleagues responded with enthusiasm, wrote their own articles, expressed their opinions, profoundly analyzed, insightful and insightful, and covered in the literary concentration. It is a valuable historical material in the history of the development of China's superhard materials industry, because she described the important historical facts and backgrounds of various periods. The history books left to future generations will have far-reaching effects.
Five years later, at the 35th anniversary of the birth of synthetic diamonds held in Hangzhou in 1998, Professor Wang wrote a "Thoughts on the Future Development of Synthetic Diamonds in China" and put forward some suggestions for its development status. Upper level; high-pressure cavity large-scale carbide anvil quality is the key; ultra-high pressure chamber is large, annual-wheel two-face anvil device has obvious advantages; product varieties should be serialized, diversified and specialized; products are artificial The development of diamond bridge; application is the development of synthetic diamond.
Since June 2012, Professor Wang has enthusiastically undertaken the important task of the 50-year history of China's superhard materials industry. After accepting the task, he took the good old days and devoted himself to it. His wholehearted dedication is very admirable! It is worth learning from our younger generation.
Fourth, pen farming is not only a lot of writing
The research project of synthetic diamond in China began in 1960. Mr. Wang participated in the whole process of diamond development and industrialization, and it was 40 years. With the development of synthetic diamonds, he enjoyed the joy of success, but More often than not sleep at night and unwilling to eat, and participate in the research. Over the past 40 years, I have shared the research results of superhard materials with my colleagues in the industry. I have written nearly one hundred articles published in various publications, which deeply reflects the author's thinking and understanding in the research and production of superhard materials.
Part of the article "Study on the Relationship between Growth of Synthetic Diamond Crystals and Pressure and Temperature" was compiled by "Artificial Diamond" (Science Press) edited by the High Pressure Synthesis Group of the Solid State Physics Laboratory of Jilin University in 1975 and edited by Professor Yan Qingquan in 1978. Solid Physical Concise Course (Higher School Trial Textbook, People's Publishing House) in two books.
In order to keep abreast of the development of foreign superhard materials research and production development, Professor Wang put forward the proposal to edit and publish the "superhard material translation set" at the 1983 Huangshan Superhard Materials Development Level Seminar. Supported by 1984-1991, the "Superhard Materials Translation Collection" edited a total of 11 episodes, nearly a million words, of which the translator provided about 100,000 words of translation, and the translation of the review was about 80,000 words, which was well received by the readers. Foreign advanced technology has contributed.
According to the goal of the middle-level technical theory teaching plan and syllabus of the abrasives industry, the abrasive training industry technician training textbook "Superhard Material Manufacturing Technology" (intermediate) is very popular for the popularization and improvement of diamond production technology. Important role.
In 1989, he was invited to teach the first superhard materials and products students of Zhengzhou Machinery College. The major was set up by the Ministry of Electrical and Mechanical Services and the State Education Commission. It is a unique specialty in domestic universities. Wang and Wang Qinsheng, Kang Jichang co-authored the first textbook for super-hard materials teaching--《Superhard materials 》.
In order to help readers have a systematic understanding of the research content, level and development of foreign cubic boron nitride and its polycrystals, the editor of Abrasives and Grinding Magazine editor Wei Fengwu wrote “Foreign cubic boron nitride manufacturingâ€. Technology" serial 12 episodes, about 60,000 words.
In 1993, the Abrasives Technical Manual (large tool book) was published by the Ordnance Industry Press. This manual summarizes the production practice of abrasives in China for 45 years, marks the technical level of abrasives in China, and brings together the technical data and common data of various abrasives at home and abroad. It is the engineering technology of abrasive abrasives and mechanical processing. Personnel, management cadres and senior and intermediate workers provided a concise, accurate and practical manual. He was the deputy editor of the large technical manual and wrote the eighth book, "Superhard Material Synthesis." In order to promote the improvement of China's cubic boron nitride crystal growth technology and broaden the application field, and accelerate the application pace, Mr. Wang led me and Li Gang engineers to compile the book "Synthesis and Application of Cubic Boron Nitride", which was reviewed during the writing process. A large amount of literature and materials, and strive to comprehensively and systematically reflect the latest achievements in the growth and application of cubic boron nitride crystals, and combine the experience and experience in scientific research and production practice to bring together the basic theory and application technology of cubic boron nitride. . The book was published by Henan Science and Technology Press in 1995 and won the second prize of the 1995 Excellent Book of Henan Province.
According to the long-term research and production of superhard materials, and the actual teaching and the cooperation of the high-tech materials of the hospital, the book "Superhard Materials" was published by Henan Science and Technology Press in 1996 and won the second prize of the 1996 Excellent Book of Henan Province. . The book has been widely used as a textbook for the Department of Superhard Materials Engineering for many years and as a technical training for the industry.
In order to adapt to the vigorous development of technical training in the super-hard materials industry, Mr. Wang combines theory with practice and focuses more on practice. The combination of popularization and improvement is more focused on the principle of popularization, with a large number of superhard material production processes and originals. In the related monographs and literatures of the auxiliary materials, the relevant content was extracted, and the book “Question and Answer of Diamond Synthesis System Engineering†was written in the form of popular answers, which was dedicated to the production of the young people engaged in the production of superhard materials. By.
In the 21st century, in the face of new challenges and enthusiasm, Wang’s 40 years of hard work should not be an individual. It should be compiled into a book as a secondary road to provide a book for technology and managers working on superhard materials. The books that can be used for reference, reading, and reference can make our career develop faster and better. This idea was quickly won by Hangzhou Gaofa Group Co., Ltd., Zhengzhou Xinzheng Electric Carbon Factory and Sino-foreign joint venture Wuxi Hengfeng. The support and funding of Cemented Carbide Products Co., Ltd., the book titled "Exploration of Synthetic Diamonds - Wang Guangzu's Proceedings" was published by Professor Zhai Qingquan of Sichuan University. He pointed out that Mr. Wang has been a fan of the past and still has an enterprising spirit. He will revitalize and develop China's diamond industry as his responsibility, and he has been working hard for the development of the industry. This book fully reflects his feelings of serving the country.
In 2001, Zhejiang University Press published the "Professional Diamond Exploration - Wang Guangzu Proceedings". This "collection of essays" embodies his rich practical experience and valuable exploration spirit, as well as deep thinking about China's future development into a world power in the development of superhard materials.
In July 2009, Zhengzhou University Press published the book "Nano-Diamond" edited by Professor Wang Guangzu. Academician Zou Guangtian of the Academy of Sciences prefaces it as a monograph in the field of nanodiamonds. In 2011, he organized industry experts as well as some young professors and doctors to preside over the preparation of Superhard Materials Manufacturing and Application Technology. This great project comes from the National Eleventh Five-Year National Key Book Publishing Program of the General Administration of Press and Publication of the People's Republic of China. Industry giants Zhongnan Diamond Company and Sifangda Company are pleased to provide funding. This is a synthesis of diamond, nanodiamond and CVD diamonds and their downstream products and application technologies covering static high temperature and high pressure catalysts. It can be seen from the fact that professors usually collect, read, extract and organize materials.
In the battle of the foundation, growth and growth of China's synthetic diamond industry, Mr. Wang has been fighting for the longest time and continues to carry out. He has achieved the most fruitful results and is still gaining harvest. He is the most respected weight of China's synthetic diamond industry. Level character.
Mr. Wang, who has been in the shackles of the year, is still taking the role of revitalizing and developing China's diamond industry in the spirit of continuous improvement. So far, he has worked hard for the development of China's superhard materials industry, fully reflecting his boxing and reporting to the country. heart. As a disciple of me, I am only admired and moved by my heart.
Mr. Wang graduated from the Chemistry Department of Wuhan University in 1956 and was assigned to the Beijing Institute of Machinery Industry Tool Science Research Institute. In 1957-1959, he was sent to the Soviet Chelyabinsk Grinding Wheel Factory and Chapolos Grinding Wheel Factory to learn the production technology of electric corundum smelting and its processing. After returning to China, he was sent to the Institute of Abrasives Grinding in the Ministry of Machinery Industry. (referred to as Sanmao) work in the abrasive research room. At the time of the establishment of the synthetic diamond development project urgently needed by the country, Sanmao was in the preparatory period, and there were only a handful of highly educated engineers and technicians. Wang Guangzu was assigned to the 121 research group and engaged in the research and development of synthetic diamonds. China's first synthetic diamond, participated in the development of China's first six-sided top press, intermediate test of artificial diamond and industrial production. It’s a lifetime.
Synthetic diamond is a high-tech developed in the 1950s. At that time, only the industrialized countries such as the United States, Sweden, Britain, the Soviet Union and Japan were in control, and the technical blockade was imposed on China. However, China’s natural diamond resources are scarce. All departments of the national economy, especially precision machinery processing, oil exploration, geological exploration and electronics industry, are in urgent need of importing from the Soviet Union and the Congo every year. In 1960, the international situation changed suddenly, and the source of diamonds was severed, which seriously affected the process of socialist construction in China. Therefore, the artificial method of manufacturing diamonds became an important issue that China urgently needed to solve. To this end, the state has developed its research as a key project 121, and in October 1960 issued a scientific research task for the development of synthetic diamond. The Joint Research Group of the General Machinery Research Institute of the First Ministry of Machinery Industry, Sanma Institute and the Geological Science Research Institute of the Ministry of Geology, including: Yu Hongchang, Wang Guangzu, Hu Enliang, Xu Jinfeng, Yao Yucheng, Zhou Jitang, Sun Rongchuan, Xiong Wensong, Lu Feixiong Yu Zhengmin, Li Jinbao, Du Fuchang, Zhang Yonghua Jin Qiuye, Liu Kaizhong. Under the guidance of the unprepared and unpredictable, Wang Guangzu and Yu Hongchang and Zhou Jitang extensively collected, collated and analyzed relevant foreign technical materials, and wrote the "Basic Synthetic Diamond Technology". The book (internal control data), and based on this, provided the first experimental program, established its own graphite-diamond balance curve, as the main basis for the selection of thermodynamic conditions of the synthesis process, and made a careful and meticulous implementation of the technical solution. arrangement.
After more than two years of cooperation in the research team, on the evening of December 6, 1963, on the domestic 300-ton type 61 double-sided anvil ultra-high pressure high-temperature device, high-purity graphite powder was used as raw material, and nickel-chromium alloy was used as catalyst. The first synthetic diamond in China was successfully synthesized under the pressure of 7.8 GPa and high temperature of 1375-1550C. Recalling the scene at the time, Professor Wang still remembers: The 32nd synthetic stick is opened, and the beautiful secret light shines. The people present can't believe it. This is the first synthetic diamond in China?! According to the X-ray diffraction analysis of the authoritative department, the spectral line is completely consistent with the natural diamond. All the members who participated in the experiment cheered for it and jumped for it. Successful! It was a memorable night and a night worthy of pride. It will serve as the beginning of China's synthetic diamond business and will last forever.
The birth of the first synthetic diamond in the land of China has become the sixth country in the world to master diamond synthesis technology. Whether it is the development of China's high-pressure high-temperature technology or the discipline of crystal growth, it is a milestone. This is very remarkable for China, which has a weak industrial base, poor economic strength, and a backward science and technology. It is able to achieve technological achievements with world-class levels. To this end, he won the 1978 National Science Conference Award.
Second, the achievements in the superhard field are remarkable
The successful development of the first synthetic diamond is only the first step in the industrialization of diamonds. In order to turn to industrial production as soon as possible, in April 1965, the Ministry of Machinery and Industry officially issued the approval document of the National Science and Technology Commission "Improved Diamond Intermediate Test Plan Task Book", clearly requiring the establishment of an intermediate test base in the three abrasives, stable synthesis process and improvement before and after Processes to achieve industrial production levels.
In cooperation with the Institute of Foundry and Forging Machinery, Sanmao began to design the DS-023A hinged six-sided anvil press with Chinese characteristics in 1964. In order to grab the speed, the principle of trial design was adopted. In 1965, 8 The monthly manufacturing installation was completed, and the first 6×6MN DS-023A press was born in China. Mr. Wang was the team leader of the process test. The members were Shao Dehou, Yu Zhichao, Kong Lingchun, Li Jinbao, Yan Juwu, etc. In the synthetic process test, the first encountered the problem of high pressure sealing. If this problem is not solved in time, the process test will be It is impossible to proceed normally. Through the observation, thinking and practice of several days, days and nights, I finally found the problem that the angle between the inclined faces of the two adjacent abutments was not suitable. A major breakthrough in high-pressure sealing technology has laid a solid technical foundation for its application in industrial production. To this end, it won the 1978 Henan Provincial Science Conference Award.
In order to raise the artificial diamond crystal growth technology to a new level, from 1966 to 1969, Mr. Wang undertook a research project with a technically difficult part—single crystal large particle synthetic diamond. The following results were obtained through experiments:
1. Obtaining a single crystal diamond of 1.0-1.5 mm which is preferably in a crystal form;
2. The success rate of synthesis on the single-pressure source six-sided anvil ultra-high pressure high-temperature device is 70%-80%, while the hinged six-sided anvil press is only 30%-40%, indicating the synchronization of the ultra-high pressure high-temperature device. The neutralization and pressure holding performance has an important influence on the stability and repeatability of the synthesis process;
3. If you want to grow gem-quality diamonds, the seeding method should be preferred;
According to the small volume of the high-pressure chamber, the temperature is difficult to control, resulting in low yield, unstable quality, high cost and economic benefits, in the late 1960s, the researchers of Sanmao Institute first proposed the hinged six-sided In the report of the "man-made diamond large single crystal research device" declared by the Ministry of Machinery, the idea of ​​designing and manufacturing a 6×25 MN hinged six-sided anvil press was proposed. Under the influence of the trend of the world's advanced technology at the time, Vice Minister Shen Hong of the Ministry of Machinery asked us to change 6×25MN to 6×50MN. The press was jointly designed by the Research Institute of Casting and Forging Machinery and Sanmao. It was manufactured by Beijing No. 2 General Machinery Factory. It was installed in Sanmao in 1974. The mechanical test shows that the design specifications basically meet the requirements. This attempt failed because the quality of the large diameter carbide anvil failed to meet the requirements for use. Although this attempt suffered setbacks, it blew the horn of marching into the large-scale press, indicating the direction of the large-scale press, which is undoubtedly the foundation stone.
In 1971, Mr. Wang collaborated with Xu Jianwen on the basis of years of practice and wrote a paper entitled “Study on the relationship between growth of synthetic diamond crystals and pressure and temperatureâ€. The relationship between diamond production, quality and pressure, and temperature is described in the paper. The laws and principles of the heating process have always guided production. According to the observed phenomenon, the critical radius rk on the relationship between the grain radius and the free energy in the system is shifted by one position. The result has caused a great academic debate. After the debate appeared, the editorial department of "Chinese Science" sent the paper. To the famous scientist Wang Daju in China, Qian Xuesen, the two old gentlemen said that if the mathematical derivation of the author's curve is correct, then how to define the rk author can completely explain according to its actual observations. Allowed, because the position of rk in the classical theory is obtained under the specific conditions of normal pressure and normal temperature, and the authors of the paper are observed under the conditions of ultra-high pressure and high temperature. The conditions of the two are very different, so rk moves a position. It is the development of traditional theory. In order to verify whether the calculation results are correct, Professor Wu Renren, a mathematician of Zhengzhou University, was invited to conduct an audit. The answer is that the calculation results are completely correct. The papers were published under the approval and support of the above-mentioned well-known professors, and they were published in both Chinese and English. Because it is a creative paper.
At the 1973 National Planning Conference, it was determined that Jilin University and Sanmao were jointly responsible for the systematic theoretical research on the growth of synthetic diamond crystals. In order to clarify this academic problem from the combination of theory and practice, experiments on the relationship between carbon materials (mainly graphite) and diamond crystal growth; experiments on the relationship between catalyst and diamond crystal growth; and carbon and catalyst before and after high pressure and high temperature X-ray diffraction analysis, according to the research results, wrote "Discussion on the mechanism of diamond crystal growth under the participation of catalysts" and "Study on the transformation of amorphous carbon to diamond structure under high pressure and high temperature". The paper clearly states: "Three non-segmentation principle of selecting catalyst" "and the "preferential principle of graphite materials", and the idea that the transformation of amorphous carbon into a diamond structure must go through a graphitization stage. This view has been incorporated into many technical monographs, becoming an axiom, which is a diamond synthesis process. A creative contribution made by technical theory.
In 1974, at the "large particle synthetic diamond" field experience exchange meeting held in Shanghai, on the growth mechanism of synthetic diamond crystals, Mr. Wang proposed that the transformation of amorphous carbon to diamond structure under high pressure and high temperature must pass through the graphitization stage, that is, in carbon. The material material plays a leading role in the structural factors during the diamond transformation process, and provides a practical basis for how to explain the diamond growth mechanism.
From 1978 to 1979, Mr. Wang undertook the key project of the Ministry - the effect of trace elements on diamond performance. The papers based on this were later selected for the 85' Super Hard Abrasive International Conference in the United States.
With the development of China's synthetic diamond industry, Mr. Wang's work is more busy. From 1981 to 1982, he participated in the research and development of high-quality fine-grain synthetic diamond, and won the second prize of scientific and technological achievements of China Nonferrous Metals Corporation. From 1991 to 1994, the research project of the Ministry of Science and Technology of the Ministry of Science and Technology - Microcrystalline cubic boron nitride. In November 1999, he was appointed as an expert of the Technical Advisory Committee of the Zhengzhou National High-tech Industrial Development Zone Management Committee, assisting in the establishment of a super-hard materials and products industrial base, and made an important contribution to Henan becoming a province of super-hard materials production. In 1983, 1986, 1988 and 1989, he won many provincial and ministerial level natural science outstanding paper awards and scientific and technological progress awards.
Third, pay attention to the frontier dedication industry
As a member of the industry, he always pays attention to relevant technology frontiers and industry development.
Promote CBN, he is active
With the reform and opening up in the 1980s, the domestic machinery industry developed. He began to pay attention to the synthesis and application of CBN in China with a keen eye. He selected the CBN raw materials, new catalysts and high pressure synthesis for the selection of my graduate thesis. As it turns out, the topic is very forward-looking. Since then, the climax of a round of CBN research is quietly emerging. Solid basic research has laid a good foundation for my future CBN production and research, which has benefited me for the rest of my life.
He also attaches importance to the exchange and promotion of domestic CBN technology. This is not his own business, nor financial support. Due to his sense of responsibility and mission to the development of China's superhard materials, he has made every effort to create conditions for industry researchers to provide a seminar and exchange. On the platform, he found the support of Wu Zhiying, the director of Zhengzhou Erqi Superhard Materials Factory. Since 1990, he has successively convened Zhengzhou, Chongqing, Lushan and other national CBN technical seminars, Sanmao, Jilin. CBN research institutes such as the University and the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences, and the CBN researchers from Shanghai Silicate Institute, Changsha Mine, Second Grinding Wheel Factory, Sixth Grinding Wheel Factory, Suzhou Grinding Wheel Factory, Shanghai Grinding Wheel Factory, etc. Extensive communication. The climax of CBN research has been set up in China: new catalysts have been used to make progress, and a series of scientific research results have been produced to synthesize high-grade cubic boron nitride of various colors, and gradually transition from laboratory to small batch pilot. With the Lushan CBN seminar as a symbol, China has ended a single, long-term stagnation of cubic boron nitride products, which has brought a new level of research and production of cubic boron nitride.
Today, many years later, China has become a big country in CBN production. We cannot forget the positive promotion of Teacher Wang.
The press is large, he advocated
The large-scale high-pressure chamber is the technical basis for achieving high-yield, high-quality, low-cost production of diamond. It is the key technology in realizing the technical parameters of the “four major†synthetic process of high-grade diamond industrialization.
It has been observed from the synthetic process test of diamond that with the continuous expansion of the high-pressure cavity, not only can the amount of diamond be increased, but more importantly, the quality of the diamond crystal is greatly improved, which provides sufficient for the production of coarse-grained and high-strength diamond. The growth space, in the mid-1960s, sprouted the idea of ​​large-scale high-pressure chamber volume. From 1966 to 1973, a 6×35 MN, 6×50 MN hinged six-face press was designed and manufactured, and the first step of the large-scale press was boldly taken. However, since the manufacturing technology of the large-diameter cemented carbide anvil has not been solved in China, the work of large-scale presses has been stranded.
From the failure of the first large-scale practice, Mr. Wang realized a very important reason, pointing out that without the high-quality carbide anvil, it is impossible to have a high-pressure cavity volume in the actual sense. Large size. The past is, now and in the future, it is still a major high-tech topic for us to fight for. For the first time, the idea of ​​large-scale high-pressure chamber is proposed, and based on this, the fourth five-year plan of China is proposed.
In order to speed up the process of expanding the volume of ultra-high pressure chambers, Xianyang Superhard Material Equipment Group Co., Ltd., Nuclear Industry Corporation 233 Factory, Aerospace Industry Administration 7803 Factory, Shanghai Shenxing Machine Manufacturing Co., Ltd., etc., have successively developed a working cylinder diameter of ф360mm ( 6×10MN) and ф400mm (6×12.5MN) hinged six-face press. For the above-mentioned company to preside over the technical argumentation of the new press design and the technical appraisal before the factory, constructive suggestions were made from the requirements of the synthetic process technology and the problems that occurred during the actual operation.
In order to further expand the volume of ultra-high pressure body in China, under the initiative of Professor Wang, the chief engineer of Hangzhou Gaofa Group, he signed a contract with Xianyang Superhard Materials Equipment (Group) Co., Ltd. in January 1997 and cooperated with Zhuzhou. XKY-6×20MN hinged six-face top press is expected to have a volume of 30~45cm3 in the synthesis chamber, which marks a new step in the large-scale of China's ultra-high pressure and high-temperature press.
Nano diamond, he actively promotes
The challenging 21st century has brought people into a critical historical period. An industrial revolution to save resources and energy and protect the ecological environment is emerging. Just like micron technology in the 1970s, nanotechnology will become the 21st century. Leading technology. Nanomaterials should of course include nanodiamonds that will play an important role.
Nanodiamonds is a very valuable member of the nanomaterial family and its properties are unparalleled in other nanomaterials. In addition to the basic characteristics inherent in diamond, nano-diamonds are, in a nutshell, simple, on the one hand, can be regarded as a "supramolecular", fully exhibiting quantum effects. On the other hand, it can also be Make a very small "macro substance" so that it shows the characteristics of the future.
Professor Wang believes that all of these will bring new challenges and opportunities to the development of superhard materials. In order to promote the further development of nano-diamond detonation synthesis technology in China, to explore its industrialization and expand the application field, Professor Wang and Professor Wu Xijun of Zhejiang University jointly planned and funded by Hangzhou Gaofa Abrasives (Group) Co., Ltd., 1997 7 In Linping, Hangzhou, the Science and Technology Commission of Zhejiang Province and the Association for Science and Technology hosted the “National First Nano-Diamond Development Seminarâ€, inviting the Lanzhou Institute of Chemical Physics, the Institute of Chemical Engineering of Gansu Province, the Second Artillery Engineering College, and the Chinese launch vehicle. Experts and professors from the Institute of Technology, Zhejiang University, Beijing Institute of Technology, Artificial Crystal Research Institute, Sanmao Institute, and Northwest Institute of Nuclear Technology have jointly discussed the industrialization of nanodiamonds and the expansion of application fields.
This is a seminar with high efficiency, high level of knowledge and rich content, representing the latest level of seminars on nanodiamond technology, production and application in China. After the meeting, he edited a collection of "Nanostructure Diamond Development Seminar". Since then, Professor Wang has had a close relationship with the research and development of nano-diamonds. In recent years, the main focus has been on the collection, collation and writing of nano-diamond synthesis technology, characteristics and application of the review or feature articles published in the "abrasives communication" In the publications such as "Industrial Diamonds" and "Superhard Materials Engineering", the use of this new technology to develop the residual heat has made his life in his later years full and meaningful.
In 2002, under the leadership of Professor Wang, Henan United Abrasives Co., Ltd., through investigations in Shenzhen, Beijing and Xi'an, built a nano-diamond production line with an annual output of 1,000 kg, filling the gap in production technology in Henan. .
The 2007 Superfine Diamond Technology Symposium was held in Beidaihe. It is jointly sponsored by State Key Laboratory of Explosion Science and Technology (Beijing Institute of Technology), Beijing Guoruisheng Technology Co., Ltd., Beijing Polystar Technology Co., Ltd., Jingri Kemei Superhard Materials Co., Ltd., and Industrial Diamond Information Network. The conference featured themes including detonation nanodiamond (DND), explosive micron polycrystalline diamond (PCD) and static pressure diamond micropowder (SND). The meeting was hosted by the Lanzhou Institute of Chemical Physics of the Chinese Academy of Sciences, one of the first nano-diamond developers, Professor Xu Kang, and the Beijing University of Technology's nano-diamond doctoral tutor, Professor Shou Shouyi and Professor Sanmao Wang.
He spares no effort in industry work
The Ministry of Machinery Industry revitalized the products in 2000, and issued a key project of "Research on the Product Revitalization Target of the Machinery Industry in 2000" to its affiliated research institutes. This is a predictive topic, which requires the organization of a group of high-level theoretical and practical experience, and the engineering and technical experts familiar with the industry to participate in the implementation. According to the arrangement of the superior, Mr. Wang and others have undertaken the sub-projects of the super-hard materials. analysis. The subject won the first prize of Science and Technology Progress Award of the Ministry of Machinery and Electronics Industry in 1988 and the second prize of National Science and Technology Progress Award in 1989.
In 1993, Shenzhen '93' China Superhard Materials Development Strategy Seminar and Celebration of the 30th Anniversary of Synthetic Diamond Development, Mr. Wang, as the chairman of the editorial committee of the conference, made the theme of “30 years of development of China's superhard materialsâ€. report. The report pointed out that China's super-hard materials industry is entering a period of critical development, the scale is expanding rapidly, the output is rising at a high speed, and the "re-entry" is approaching, facing fierce international competition. Opportunities and challenges coexist at this important moment. Where to go, you need to think hard and make choices! In line with the 30th anniversary of the birth of China's first synthetic diamond, Sanmao hosted the "China Superhard Materials Industry Development Strategy Seminar" based on the initiative of old experts and veteran comrades who are closely concerned about the development of superhard materials industry. Colleagues responded with enthusiasm, wrote their own articles, expressed their opinions, profoundly analyzed, insightful and insightful, and covered in the literary concentration. It is a valuable historical material in the history of the development of China's superhard materials industry, because she described the important historical facts and backgrounds of various periods. The history books left to future generations will have far-reaching effects.
Five years later, at the 35th anniversary of the birth of synthetic diamonds held in Hangzhou in 1998, Professor Wang wrote a "Thoughts on the Future Development of Synthetic Diamonds in China" and put forward some suggestions for its development status. Upper level; high-pressure cavity large-scale carbide anvil quality is the key; ultra-high pressure chamber is large, annual-wheel two-face anvil device has obvious advantages; product varieties should be serialized, diversified and specialized; products are artificial The development of diamond bridge; application is the development of synthetic diamond.
Since June 2012, Professor Wang has enthusiastically undertaken the important task of the 50-year history of China's superhard materials industry. After accepting the task, he took the good old days and devoted himself to it. His wholehearted dedication is very admirable! It is worth learning from our younger generation.
Fourth, pen farming is not only a lot of writing
The research project of synthetic diamond in China began in 1960. Mr. Wang participated in the whole process of diamond development and industrialization, and it was 40 years. With the development of synthetic diamonds, he enjoyed the joy of success, but More often than not sleep at night and unwilling to eat, and participate in the research. Over the past 40 years, I have shared the research results of superhard materials with my colleagues in the industry. I have written nearly one hundred articles published in various publications, which deeply reflects the author's thinking and understanding in the research and production of superhard materials.
Part of the article "Study on the Relationship between Growth of Synthetic Diamond Crystals and Pressure and Temperature" was compiled by "Artificial Diamond" (Science Press) edited by the High Pressure Synthesis Group of the Solid State Physics Laboratory of Jilin University in 1975 and edited by Professor Yan Qingquan in 1978. Solid Physical Concise Course (Higher School Trial Textbook, People's Publishing House) in two books.
In order to keep abreast of the development of foreign superhard materials research and production development, Professor Wang put forward the proposal to edit and publish the "superhard material translation set" at the 1983 Huangshan Superhard Materials Development Level Seminar. Supported by 1984-1991, the "Superhard Materials Translation Collection" edited a total of 11 episodes, nearly a million words, of which the translator provided about 100,000 words of translation, and the translation of the review was about 80,000 words, which was well received by the readers. Foreign advanced technology has contributed.
According to the goal of the middle-level technical theory teaching plan and syllabus of the abrasives industry, the abrasive training industry technician training textbook "Superhard Material Manufacturing Technology" (intermediate) is very popular for the popularization and improvement of diamond production technology. Important role.
In 1989, he was invited to teach the first superhard materials and products students of Zhengzhou Machinery College. The major was set up by the Ministry of Electrical and Mechanical Services and the State Education Commission. It is a unique specialty in domestic universities. Wang and Wang Qinsheng, Kang Jichang co-authored the first textbook for super-hard materials teaching--《Superhard materials 》.
In order to help readers have a systematic understanding of the research content, level and development of foreign cubic boron nitride and its polycrystals, the editor of Abrasives and Grinding Magazine editor Wei Fengwu wrote “Foreign cubic boron nitride manufacturingâ€. Technology" serial 12 episodes, about 60,000 words.
In 1993, the Abrasives Technical Manual (large tool book) was published by the Ordnance Industry Press. This manual summarizes the production practice of abrasives in China for 45 years, marks the technical level of abrasives in China, and brings together the technical data and common data of various abrasives at home and abroad. It is the engineering technology of abrasive abrasives and mechanical processing. Personnel, management cadres and senior and intermediate workers provided a concise, accurate and practical manual. He was the deputy editor of the large technical manual and wrote the eighth book, "Superhard Material Synthesis." In order to promote the improvement of China's cubic boron nitride crystal growth technology and broaden the application field, and accelerate the application pace, Mr. Wang led me and Li Gang engineers to compile the book "Synthesis and Application of Cubic Boron Nitride", which was reviewed during the writing process. A large amount of literature and materials, and strive to comprehensively and systematically reflect the latest achievements in the growth and application of cubic boron nitride crystals, and combine the experience and experience in scientific research and production practice to bring together the basic theory and application technology of cubic boron nitride. . The book was published by Henan Science and Technology Press in 1995 and won the second prize of the 1995 Excellent Book of Henan Province.
According to the long-term research and production of superhard materials, and the actual teaching and the cooperation of the high-tech materials of the hospital, the book "Superhard Materials" was published by Henan Science and Technology Press in 1996 and won the second prize of the 1996 Excellent Book of Henan Province. . The book has been widely used as a textbook for the Department of Superhard Materials Engineering for many years and as a technical training for the industry.
In order to adapt to the vigorous development of technical training in the super-hard materials industry, Mr. Wang combines theory with practice and focuses more on practice. The combination of popularization and improvement is more focused on the principle of popularization, with a large number of superhard material production processes and originals. In the related monographs and literatures of the auxiliary materials, the relevant content was extracted, and the book “Question and Answer of Diamond Synthesis System Engineering†was written in the form of popular answers, which was dedicated to the production of the young people engaged in the production of superhard materials. By.
In the 21st century, in the face of new challenges and enthusiasm, Wang’s 40 years of hard work should not be an individual. It should be compiled into a book as a secondary road to provide a book for technology and managers working on superhard materials. The books that can be used for reference, reading, and reference can make our career develop faster and better. This idea was quickly won by Hangzhou Gaofa Group Co., Ltd., Zhengzhou Xinzheng Electric Carbon Factory and Sino-foreign joint venture Wuxi Hengfeng. The support and funding of Cemented Carbide Products Co., Ltd., the book titled "Exploration of Synthetic Diamonds - Wang Guangzu's Proceedings" was published by Professor Zhai Qingquan of Sichuan University. He pointed out that Mr. Wang has been a fan of the past and still has an enterprising spirit. He will revitalize and develop China's diamond industry as his responsibility, and he has been working hard for the development of the industry. This book fully reflects his feelings of serving the country.
In 2001, Zhejiang University Press published the "Professional Diamond Exploration - Wang Guangzu Proceedings". This "collection of essays" embodies his rich practical experience and valuable exploration spirit, as well as deep thinking about China's future development into a world power in the development of superhard materials.
In July 2009, Zhengzhou University Press published the book "Nano-Diamond" edited by Professor Wang Guangzu. Academician Zou Guangtian of the Academy of Sciences prefaces it as a monograph in the field of nanodiamonds. In 2011, he organized industry experts as well as some young professors and doctors to preside over the preparation of Superhard Materials Manufacturing and Application Technology. This great project comes from the National Eleventh Five-Year National Key Book Publishing Program of the General Administration of Press and Publication of the People's Republic of China. Industry giants Zhongnan Diamond Company and Sifangda Company are pleased to provide funding. This is a synthesis of diamond, nanodiamond and CVD diamonds and their downstream products and application technologies covering static high temperature and high pressure catalysts. It can be seen from the fact that professors usually collect, read, extract and organize materials.
In the battle of the foundation, growth and growth of China's synthetic diamond industry, Mr. Wang has been fighting for the longest time and continues to carry out. He has achieved the most fruitful results and is still gaining harvest. He is the most respected weight of China's synthetic diamond industry. Level character.
Mr. Wang, who has been in the shackles of the year, is still taking the role of revitalizing and developing China's diamond industry in the spirit of continuous improvement. So far, he has worked hard for the development of China's superhard materials industry, fully reflecting his boxing and reporting to the country. heart. As a disciple of me, I am only admired and moved by my heart.
