Sic Black Silicon Carbide Abrasive Electric Resistance For Casting
Excellent Price Electric Resistance Silicon Carbide Sic Black Abrasive For Casting
Silicon carbide (SiC) is a covalent compound composed of carbon (C) and silicon (Si) with very strong covalent bonds. Silicon carbide has a series of advantages such as high thermal conductivity, high hardness, oxidation resistance, corrosion resistance, and low price. It is widely used as an abrasive in industrial grinding processes.
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw marterials .Its hardness is between fused alumina and synthetic diamond.Mechanical intensity of it is higher than fused alumina .It is brittle and sharp has electrical and heat conductivity in some degree.
Function
it is widely used in glass industry, ceramic industry, stone industry, refractory industry, iron industry, non-ferrous industry and so on. Green silicon carbide has good self-sharpening, and is mostly used for processing hard alloy, titanium alloy and optical glass, and also for honing cylinder liner and accurate grinding HSS tool.

Applications
Silicon carbide has stable chemical property, high thermal conductivity coefficient, small thermal expansion coefficient and good abrasion resistance. Besides being used as abrasive, it has many other purposes. For example, silicon carbide powder is coated on the inner wall of turbine impeller or cylinder block by special process to improve its abrasion resistance and extend its service life by 1-2 times; It is a kind of advanced refractory material made of it, which is resistant to thermal shock, small in size, light in weight and high in strength, and has good energy saving effect. Low-grade silicon carbide (containing about 85% SiC) is a good deoxidizer, which can accelerate the speed of steel making, facilitate the control of chemical composition and improve the quality of steel. In addition, silicon carbide is also widely used to make silicon carbon rods for electric heating elements.
