Because of its stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and good wear resistance, silicon carbide has many other uses besides abrasives, such as: coating silicon carbide powder on turbine impellers or cylinder blocks by special processes. The inner wall can improve its wear resistance and prolong the service life by 1 to 2 times; the advanced refractory material used to make it is resistant to shock, small in size, light in weight, high in strength, and has good energy-saving effect. Using it can speed up the speed of steel making, and it is easy to control the 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.
