Refractory silicon carbide

Refractory Silicon Carbide the industrial production method of silicon carbide is to use high-quality quartz sand and petroleum coke to be refined in a resistance furnace. The refined silicon carbide blocks are crushed, acid-base washed, magnetic separation and sieving or water selection to make products of various particle sizes.

Silicon carbide has four main application areas, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials.

As an abrasive, it is mainly used to make grinding and polishing of grinding wheels, sandpapers, belts, whetstones, grinding blocks, grinding heads, grinding pastes and photovoltaic products, such as monocrystalline silicon, polycrystalline silicon and piezoelectric crystals in the electronics industry.

As a metallurgical raw material, silicon carbide has the characteristics of corrosion resistance, high temperature resistance, high strength, good thermal conductivity, and impact resistance. On the one hand, silicon carbide can be used for various smelting furnace linings, high temperature furnace components, silicon carbide plates, lining plates, and supports Pieces, saggers, silicon carbide crucibles, etc. On the other hand, it can be used as a high-temperature indirect heating material in the non-ferrous metal smelting industry
