On September 28, experts from the National Special Minerals Materials Engineering Technology Research Center of Guilin Institute of Mineral Geology revealed that the world now produces 5 billion carats of synthetic diamond per year, of which 4 billion carats are produced in China, accounting for the international market. Eighty percent, China has become the world's largest diamond in the world.
It is reported that in the 1950s, synthetic diamond was first successfully developed and applied in the United States. In the 1960s, China developed synthetic diamonds with independent intellectual property rights. It was widely used in the geological drilling industry and other fields in the 1970s.
After several decades of development, China's various tools with independent intellectual property rights, which are made of synthetic diamonds as superhard materials, have also been widely used in machining, stone cutting, geological drilling, electronics, and defense industries, and have regained the experience of foreign manufacturers. In the market of 70% of the monopoly, in recent years, it has begun to make great strides to go abroad and move to the international market.
At present, there are more than 200 synthetic diamond manufacturers in China, distributed in various provinces, municipalities and autonomous regions in China. The manufacturers with large scale and large output are mainly distributed in Zhengzhou, Henan, Guilin, Tianjin, Guizhou, Beijing and other places in Guangxi. In addition to domestic demand, it is mainly exported to Europe, America and Asia Pacific.
Experts here said that synthetic diamond is a kind of artificial crystal. In the 21st century, various artificial crystals are increasingly replaced as key materials in the high-tech fields such as microelectronics, optoelectronics, telecommunications, aerospace, aerospace and modern military technology. The importance of scientists from all over the world.
After more than half a century of development, China's artificial crystal industry has achieved remarkable achievements. Many kinds of artificial crystal growth technology ranks internationally advanced or advanced. Only Guilin Institute of Mineral Geology has many advanced international standards. China's blank artificial crystal technology such as emerald, corundum, cubic boron nitride and zinc oxide with independent intellectual property rights. China's brand of nonlinear optical crystals has a worldwide reputation. Some important crystals have met the needs of major domestic projects. A number of high-tech synthetic crystal crystals have been exported abroad.
