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