Basic Introduction To Silicon Carbide

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 needs to be added when producing green silicon carbide) through a resistance furnace. Silicon carbide is a semiconductor that exists in the form of the extremely rare mineral moissanite in nature. Since 1893, it has been produced on a large scale as powders and crystals, used as abrasives, etc. Among non oxide high-tech refractory 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. Chinese industrial production of silicon carbide is divided into two types: black silicon carbide and green silicon carbide, both of which are hexagonal crystals.
