Product Description

Application
Silicon carbide is an inorganic substance with the chemical formula of SiC. Due to its stable chemical properties, high thermal conductivity, small thermal expansion coefficient and good wear resistance, silicon carbide has many other uses besides being used as abrasive. For example, coating silicon carbide powder on the inner wall of turbine impeller or cylinder block with special process can improve its wear resistance and prolong its service life by 1 ~ 2 times; The high-grade refractory material made of it has the advantages of heat shock resistance, small volume, light weight, high strength and good energy-saving effect. Low grade silicon carbide (containing about 85% SiC) is an excellent deoxidizer, which can speed up the steelmaking speed, facilitate the control of chemical composition and improve the quality of steel. In addition, silicon carbide is also widely used to make silicon carbide rods for electric heating elements.
