Silicon carbide, also known as emery, is made of quartz sand, petroleum coke (or coal coke), wood chips (need to add salt when producing green silicon carbide) and other raw materials through high temperature smelting resistance furnace. Silicon carbide also has rare minerals in nature. In contemporary C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide is the most widely used and the most economical kind, which can be called gold and steel sand or refractory sand. At present, the industrial production of silicon carbide in China is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals with a specific gravity of 3.20 ~ 3.25 and a microhardness of 2,840 ~ 3,320 kg/mm2.
Silicon carbide was established in 1891 by American Acheson fused diamond experiment, accidentally discovered a carbide in the laboratory, was mistaken for diamond mixture, so named emery, Acheson study out 1893 industrial smelting silicon carbide method, namely we often say that Acheson furnace, has been in use today, with the carbon materials for furnace core body resistance furnace, electric heat quartz SIO2 mixture formation of silicon carbide and carbon. Silicon carbide was first found in meteorites in 1905; In 1907, the first silicon carbide crystal led was born. In 1958, the first World Silicon Carbide Conference was held in Boston for academic exchange. From 1987 to now, the production line of silicon carbide was established based on the research results of CREE, and suppliers began to provide commercial silicon carbide.
Silicon carbide can be used as abrasive, can be used to make abrasive, such as grinding wheel, whetstone, grinding head, sand tile; As metallurgical deoxidizer and high temperature resistant material; High purity single crystal, can be used to manufacture semiconductor, manufacture silicon carbide fiber.
