SIC/Black Silicon Carbide micropowder for polishing 1. 99%sic 2. manufacturer for 10 years 3. FEPA,JIS  

Black silicon carbide micropower is produced at hight temperature in an electric resistancetype furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synathetic diamond. Mechanical intensity of it is hig-her than fused alumina.it is brittle and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron,non-ferrous metal,rock,leather,rubber,etc. It is also broadly used as refractory material and metallurgical additive.

Black silicon carbide micropower is made by heating silica sand and petroleum coke packed around electrodes in an electric resistance furnace to above 2200°C. This material is very resistant to abrasion and to corrosion with a molten slag. It also has excellent resistance to thermal spalling. However as it is a carbide, it will oxidise readily. With respect to other refractory aggregates silicon carbide has a fairly high conductivity.
