What is the Silicon carbide

Silicon carbide and silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips (green silicon carbide production need to add salt) such as raw material through high temperature electric resistance furnace smelting. There is also a rare mineral silicon carbide in nature, and the mo SangShi. Silicon carbide is also called the moissanite. In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic, can be called corundum or refractory sand. At present China's industrial production of silicon carbide is divided into two black silicon carbide and green silicon carbide, are the six-party crystal, specific gravity is 3.20 ~ 3.20, the microhardness of 2840 ~ 3320 kg/was.
