On July 17, 2018, China Machine Tool Industry Association Superhard Materials Branch (hereinafter referred to as "Super Association"), Beijing University of Aeronautics and Astronautics School of Materials Science and Engineering and Beijing Mentougou District Science and Technology Committee co-sponsored China's superhard materials industry The development workshop was held in Beijing. The meeting invited the former vice president of the Chinese Academy of Engineering and the director of the National New Materials Expert Advisory Committee to attend and preside over the meeting. Also present at the meeting were academicians of the Chinese Academy of Sciences, Zou Guangtian and Tian Yongjun, Professor Zhang Tao of the School of Materials Science, Beijing University of Aeronautics and Astronautics, Li Shichun, director of the Mentougou Science and Technology Committee of Beijing, and related experts of the Super Association Technical Expert Committee and Wang Jiancai, Chairman of Beijing Shenzhou Lingshan New Materials Co., Ltd. Sixteen people.
During the presiding meeting, the academician said that the new material is the key guarantee for the development of the national economy and the key guarantee for the industrial development of high-end manufacturing and national defense. It is the focus of strategic competition among countries. "One generation of materials, one generation of industry", from the application history of materials, it can be seen that every development of human productivity is accompanied by the progress of materials. The discovery, invention and application of new materials are inextricably linked to technological revolutions and industrial changes. Academician said that at present and in the future, the core task requirements for the development of China's new materials industry are: 1 focus on the major national strategic needs and industrial development bottlenecks, and enhance the support capabilities of key strategic materials; 2 promote the intelligentization of the production process and Green transformation, improve the international competitiveness of advanced basic materials; 3 speed up the layout of cutting-edge new materials, and seize the commanding heights of the future development of the global new materials industry. Academician also mentioned that superhard materials are widely used in national economic construction and are indispensable advanced basic materials and high-functional materials in strategic emerging industries. The purpose of convening this symposium today is to hope to have a deeper and more comprehensive understanding of the latest developments in China's superhard materials industry, and to see what difficulties and bottlenecks are faced in the upstream and downstream industries, the development of the industry and the ecological environment, from the Chinese Academy of Engineering. What support can be provided by the new material leadership group, industry associations, and local government levels to better support the sustainable and healthy development and growth of China's superhard materials industry in order to better serve China's manufacturing and economic development.
During the discussion, Prof. Li Zhihong, Senior Consultant and Senior Director of the Expert Committee of the Super Association, used a series of data to comprehensively and systematically introduce the development history of superhard materials and the dominant position in the international market today. He said that China is super hard. After more than 50 years of development, the material has experienced a process from scratch, from small to large, from weak to strong. Now it has stood firmly in the world's first position, and constantly seeks ultra-precision machining and functional components. The application and other aspects have surpassed the world's advanced level. This industry that relies entirely on China's independent intellectual property rights development deserves our pride. Academician Tian Yongjun mentioned that China's superhard materials industry is unique in the field of materials, without obtaining national support plans and Under the premise of special projects and other major projects, it is hard-won to rely on the industry's talented people to make the industry affect the level of the world. I hope that relevant parties can learn more about this industry and learn this growth mode. Supporting the development of national industries; Professor Zhang Tao said that the future development of superhard materials will not be limited to "superhard". Single crystal diamonds with excellent properties such as electricity, optics, mechanics, acoustics and thermals will solve a series of problems. For example, diamond electronic devices have advantages such as small size, high integration, high power and no need for cooling. Will lead to a new generation of semiconductor technology revolution.
Participants also mentioned in the discussion that the development of any material is inseparable from the support of raw materials. Pyrophyllite is an irreplaceable insulation, insulation, sealing and pressure transfer medium that must be used in the production of superhard materials. Wang Zhiming, director of the Super-Technical Expert Committee, and many other professors said that although there is a certain distribution of pyrophyllite deposits in China, it has been proved by many batches of industry experts and numerous experimental studies to prove the pyrophyllite of Mentougou in Beijing. Special geological origin, most suitable for diamond synthesis. The pyrophyllite is a high-aluminum type, and its biggest characteristic is that it has superior insulation and pressure-conducting properties at high temperatures compared with domestic similar ores, and has more stable physical and chemical properties, and is widely used in the domestic synthetic diamond industry. The development of the national economy is inseparable from the support of super-hard materials, and the development of the super-hard materials industry is inseparable from the support of pyrophyllite. It is hoped that relevant parties can pay attention to the healthy and orderly development of pyrophyllite.
In his concluding remarks, the academician said that superhard materials are an important and unique sector in the field of new materials, in major projects such as oil exploration and mining, high-end machine tools and automobile manufacturing, rail transit, nuclear power, national defense military and aerospace. And a pivotal position in the field of photovoltaics and electronic information. In general, the technical level and product quality of China's superhard materials have reached the world's advanced level, but there are short-boards in the high-end industries, and they are heavily dependent on imports in deep processing of materials and high-end tools. In addition, superhard materials have been using their mechanical properties to process known materials, and diamond's unparalleled functionality is still being explored. It is expected to be industrially produced in the future, using its excellent thermo-optical properties for cosmic rays. The “Diamond Age†is expected to be in the forefront of protection, cutting-edge weapons and equipment, stealth and anti-corrosion, improving missile flight speed and strike accuracy, high-power laser detection, large-scale integrated circuits and LED new light source heat sink.
After the meeting has completed the established issues, a meeting minutes will be formed for the reference of relevant departments.
