Silicon carbide is a carbonized substance formed by synthetic carbonization, generally at a high temperature of 2,000 degrees Celsius, when carbon and silicon dioxide are energized. Because silicon carbide has the advantages of abrasion resistance, substance hardness, corrosion resistance, and high strength at high temperatures, it is used in a variety of abrasion-resistant, high-temperature-resistant, and other work in the parts. Silicon carbide is a semiconductor at room temperature and has impurity conductivity. The higher the purity of silicon carbide with the temperature also gradually increase the resistivity naturally decreases, according to the silicon carbide containing impurities, the conductivity is different, and silicon carbide hydrophilic, far-infrared radiation and so on.
Silicon carbide can be used in the abrasive abrasives, as ingredients for the production of grinding wheels, sandpaper, grinding blocks, as well as the electronics industry in the piezoelectric crystal aspects of the grinding, polishing role. Because of silicon carbide corrosion resistance, high temperature resistance, good thermal conductivity, good impact resistance can be used as smelting furnace lining, silicon carbide plate, silicon carbide crucible, lining plate. At the same time, it can also be used as high temperature indirect heating material for non-ferrous metal smelting industry.
In short, silicon carbide has many uses, can be widely used in different fields, and in different fields, play a role.
