Product Description
Black Silicon Carbide, Black SiC for Abrasives
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. Its hardness is between fused alumina and synthetic diamond. The mechanical intensity of it is higher than that of fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. Black silicon carbide is suitable for grinding cast iron, non-ferrous metal, leather, rubber, wood, rock, it also be used as high grade refractory material.
Advantages:
Black Silicon Carbide (SiC) is a man made mineral of extreme hardness and sharpness. It is the ideal abrasive for grinding / sanding materials of low tensile strength such as Cast Iron, Brass, Aluminum, Bronze etc. Its thermal properties make it an excellent medium for use in the manufacture of refractory products and crucibles.
Application:
Grinding wheels
Abrasive products
Lapping , Polishing
Refractory raw materials
Packing
1.25kg woven bag,40 woven bags/jumbo bag/pallet
2.25kg paper bag,40 paper bags/pallet
