Silicon carbide is an inorganic substance with the chemical formula SiC. It is produced by high-temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and sawdust (salt is required to produce green silicon carbide) through a resistance furnace. Silicon carbide also exists as a rare mineral in nature, mosonite. Among non oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical one, which can be called steel sand or refractory sand. The silicon carbide produced by Chinese industry is divided into two types: 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 2840-3320kg/mm
