Silicon carbide due to stable chemical performance, high thermal conductivity, small thermal expansion coefficient, good wear resistance,
in addition to abrasive use, there are many other USES, such as: the special process of silicon carbide powder coated on the inner wall of the turbine impeller or cylinder body,
can improve its wear resistance and extend the service life 1~2 times; It is made of high - grade refractory with heat - resistant shock, small size, light weight and high strength.
Low grade silicon carbide (containing about 85% SiC) is an excellent deoxidizer. It can speed up steel making, control chemical composition and improve steel quality. In addition,
silicon carbide is also widely used in the fabrication of heating elements.
The hardness of silicon carbide is very high. Mohs hardness is 9.5, second only to the hardest diamond in the world (grade 10).
With excellent thermal conductivity, silicon carbide is a kind of semiconductor and can resist oxidation at high temperature.
