Product Description
Black Silicon Carbide
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials .Its hardness is between fused alumina and synthetic diamond.Mechanical intensity of it is higher than fused alumina .It is brittle and sharp 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.

Production Process
1.Anthracite or petroleum coke is mixed with silica sand to add other auxiliary materials, and is also made into mixed silicon carbide through graphite electrode.
2.Manual sorting of silicon carbide blocks of different purity.
3.Jaw Crusher → Screening → Particle Crushing (Bamak Crusher) → Screening→ Packaging → Storage
