On March 9, 2012, Dr. Lu Kewen and Ding Lei from the School of Environment and Planning of Henan University and the Humanities and Social Sciences Department of the Ministry of Education, Huang He Civilization and Sustainable Development Research Center visited China Superhard Materials Network to investigate the development history, current situation and trend of China's synthetic diamond industry. . Received warm reception from General Manager Liu Jinchang of China Superhard Materials Network. 
Dr. Lu Kewen hopes to see Professor Wang Guangzu. On March 10, 2012, Professor Liu Jinchang invited Professor Wang Guangzu, a consultant of China Superhard Materials Network, to the website of Superhard Materials. Dr. Lu Kewen asked Professor Wang for research and research. General Manager Liu Jinchang and Professor Wang Guangzu gave a detailed introduction to Dr. Lu Kewen. From December 6, 1963, the first synthetic diamond was successfully developed by the First Institute of Mechanical Industry Abrasives and Abrasives. In 1965, it was cooperated with Sanmao. Under the development of a machine forging and pressing machinery research institute, the hinged six-face diamond synthesis press with independent intellectual property rights in China was successfully developed. The three-face top press machine used in casting and forging was synthesized by the three grinding machine Wang Guangzu. In 1966, Sanmao completed the diamond intermediate test mission issued by the Ministry. In the same year, it produced 10,000 carats of diamonds, providing a complete set of process and factory design process materials and commitments for the first artificial diamond and product factory in China. The training of technicians and workers of Liusha has created a precedent for the industrialized production of synthetic diamonds and products in China. At the same time, in addition to the three mills, the technology is transferred to related companies in the abrasives industry. And warmly receive training from the coal, petroleum, metallurgy, geological and other industries. It has played a vital role in the development of China's diamond industry. In 1993, China's synthetic diamond production reached more than 200 million carats, becoming the world's largest producer of synthetic diamonds. After nearly 50 years of development, it is a high-speed development in the past ten years. With the implementation of the large-scale hinged six-face press, the advancement of automatic control technology and the popularization of the powder synthesis process, the quality of diamond production in China has been achieved. Double breakthrough. In 2010, China's synthetic diamond production was 9.2 billion carats, accounting for 90% of the world's total synthetic diamond production. Henan's synthetic diamond production accounted for 80% of the country's total output. At present, China's synthetic diamond industry has formed an intensive and large-scale production pattern. The rapid improvement of enterprise innovation capability has become the mainstay of innovation. From 400#-1500# fine-grained diamond, abrasive grade diamond to 2.4mm-2.6mm gem-quality diamond can be produced; at the same time, China's 7mm-10mm synthetic diamond large single crystal has remarkable scientific research results. At present, China's superhard materials industry has entered the ranks of world powers. My superhard materials have also become the world's largest producers. At the same time as the results of the static pressure diamond in China. The research and production of non-static pressure diamond in China has been quickly followed up with remarkable results. Dynamic high temperature and high pressure method, namely detonation method, explosion method nanodiamond and low pressure high temperature method, ie, vapor phase chemical deposition diamond film (CVD), the quality is rapidly improved, and mass production is possible. In order to lay a foundation for the functional use of diamond, I have been following up on the functional application of diamond in thermal, optical, electrical and acoustic applications. Superhard materials have been included in the new materials in the strategic emerging industries of the National 12th Five-Year Plan. China's machine tool industry "12th Five-Year Plan" put superhard materials and products into key development products. It is believed that China's super-hard materials and products industry will have greater development, and it will not be far from full development.
