Silicon carbide product introduction:
Black silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips and other raw materials through high-temperature smelting in a resistance furnace. It is black opaque, hexagonal crystal, and the Mohs hardness is 9.15.
Silicon carbide is very hard and has excellent thermal conductivity. It is a semiconductor and can resist oxidation at high temperatures. It is mainly used for grinding and polishing of grinding wheels, artificial stones, sandstone, sandpaper, abrasive belts, oil stones, grinding blocks, grinding heads, grinding pastes, monocrystalline silicon, polycrystalline silicon in photovoltaic products, and piezoelectric crystals in the electronics industry.
