Silicon Carbide

Silicon carbide, also known as moissanite and emery, is an inorganic substance with a chemical formula of SiC. It is made of quartz sand, petroleum coke (or coal coke), wood chips (salt is needed to produce green silicon carbide) and other raw materials are smelted at high temperature in a resistance furnace. Among the non-oxide high-tech refractory materials such as C, N, B, silicon carbide is the most widely used and most economical one. It can be called silicon carbide. Moissanite is also a rare mineral in nature. The silicon carbide produced in China’s industry is divided into black silicon carbide and green silicon carbide. Hexagonal crystals are connected in series with a specific gravity of 3.20~3.25 and a micro hardness of 2840~3320kg/mm2.
