SIN ceramic grinding ball

High temperature structure material

Sic ceramic product has the advantages of excellent corrosion resistance, 

high coefficient of heatconductivity,self-lubricity,small expansion and so on.

It can be widely used in the petroleum,chemical,machinery building,

metallurgical industry and motors industries.The frictional factor of combinationof silicon carbide and 

carbongraphite is the least.
