Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips as raw material through high temperature electric resistance furnace smelting.There is also a rare mineral silicon carbide in nature CalledMo SangShi Stone.Silicon carbide is also called the moissanite.In contemporary C, N, B and other non-oxide high-tech refractory raw materials, Silicon carbide is the most widely used and economical type, and it can be called gold steel sand or refractory sand.At present, China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide, both hexagonal crystals, specific gravity of 3.20 ~ 3.25, microhardness of 2840 ~ 3320kg / mm2.
1.Silicon carbideused for 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal wire cutting. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry, engineering materials.
2. Silicon carbide for semiconductor, lightning rod, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutch, diesel particulate filter, filament pyrometer, ceramic film, cutting tools, heating elements , Nuclear fuel, jewelry, steel, protective gear, catalyst support and other fields.
3. Abrasives---Silicon carbide is mainly used in the production of grinding wheel, sandpaper, abrasive belt, whetstone, grinding block, grinding head, grinding paste and photovoltaic products in monocrystalline silicon, polycrystalline silicon and piezoelectric crystal and other aspects of the industry, such as grinding, polishing and so on.
4. Chemical industry---Silicon carbide can be used as steel-making deoxidizer and cast iron tissue modifier and silicon tetrachloride raw materials.
