DESCRIPTION
Silicon carbide is produced by hot melting in a resistance furnace. The raw materials include quartz sand, petroleum coke (or coal coke) and wood chips (salt is needed to produce green silicon carbide). It is called gold and steel sand or refractory sand. At present, industrial silicon carbide production is divided into black silicon carbide and green silicon carbide, they are hexagonal crystals, specific gravity of 3.20-3.25, microhardness of 2840-3320kg/mm2. So what is silicon carbide used for? Next Henan 40% small edition for you to answer!
Silicon carbide has four main uses: functional ceramics, high-grade refractory materials, abrasives and metallurgical raw materials. Crude silicon carbide material has been supplied in large quantities, can not be regarded as high-tech products. The application of nano-sized SIC powder with very high technical content cannot generate economies of scale in a short time.
