Product Features
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 good in energy saving effect.
