Product Overviews Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Black silicon carbide is fragile and sharp, and has certain electrical and thermal conductivity. It have been used for processing glass,refractory materials,ceramic,stone,cast iron and other metal. Advantages:  (1) Special treated products get higher purity, better toughness, and better grinding effect (2) Higher purity and less impurities (3) Chemical washed and water washed good cleanness. (4) Good hardness,Corrosion resistance  The chemical index SIC 97-99 F.C 0.2-0.3 Fe2O3 0.3-0.8 Application: 1.Coated the inner wall of water wheel, impeller, cylinder to provide abrasion resistance and prolong life.
