Introduction and Major Applications of Silicon Carbide

Silicon carbide (SiC) is electrical fused in an electric resistance furnace smelting from quartz sand, petroleum coke (coal tar), wood chips and other raw materials. There is also rare mineral of silicon carbide in the nature – Moissanite, and silicon carbide is also called moissanite. 

In contemporary C, N, B and other high technology non-oxide refractory raw materials, silicon carbide is the most widely used and also one of the most economic materials, which can be called carborundum or refractory sand. At present, China's industrial silicon carbide is divided into black silicon carbide and green silicon carbide, which are the six-party crystal, and the specific gravity is 3.20 ~ 3.25, the micro hardness of 2840 ~ 3320 kg/mm2.

Silicon carbide mainly has four application fields, that is, functional ceramics, refractories, abrasives and metallurgical raw materials. Silicon carbide coarse material has been in abundant supply, so it can't be considered as high-tech products. And the application of high technology nano-sized silicon carbide powder can't form scale economy at a short time.

A. As abrasives: it can be used to make abrasive products, mainly used for grinding wheel, abrasive paper, abrasive belt, abrasive stone, grinding segments, grinding head, grinding paste and monocrystalline silicon, polycrystalline silicon of photovoltaic products and the grinding, polishing of piezoelectric crystal in the electronic industry, etc.

B. As metallurgical deoxidizer and high temperature resistant material: Silicon carbide deoxidizer is a new kind of compound deoxidizer, which replaces the traditional solid silicon powder carbon powder and has more various and stable physical and chemical performance compared with the original process. In addition, its deoxidization effect is good. It shortens the deoxidize time, save energy, improve the efficiency of steel and the quality of steel, reduce the raw material consumption, reduce the environmental pollution, improve the working conditions and  the comprehensive economic benefits of the electric furnace. It really has important value.

C. Silicon carbide can be used for all kinds of smelting furnace lining, high temperature furnaces artifacts, silicon carbide plate, lining board, strutting piece and silicon carbide crucible by using corrosion resistance, high temperature resistance, great strength, good thermal conductivity and impact resistance and other properties of silicon carbide.

D. By using the coefficient of thermal conductivity, thermal radiation, the characteristics of high strength, it can manufacture sheet kiln furniture, which not only reduces the capacity of kiln furniture, but also improves the loading capacity and the product quality of the kiln. It shortens the production cycle and is the ideal indirect materials of ceramic glaze baking sintering.

Main applications: used for the wire cutting of monocrystalline silicon of 3-12 inches, polycrystalline silicon, potassium arsenide, quartz crystal, and solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry physical processing materials; Used in semiconductor, the lightning rod, circuit components, the application of high temperature, ultraviolet detection apparatus, material structure, astronomy, disc brakes, clutch, diesel particle filter, filaments pyrometer, ceramic film, cutting tools, heating element, nuclear fuel, jewelry, steel, safety gear, catalyst supporter and other fields.
