Product Description

Product introductions:

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw marterials .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.

Applications
1.ceramic,glass,stone,refractory material,cast iron and nonferrous metals,etc.
2.As abrasive,silicon carbide can be used for abrasive tools, such as grinding wheel,oilstone,grinding,sand tile etc.
3.As metallurgical deoxidizer and high temperature resistance materials.
4.As the single crystal of high purity,silicon carbide can be used for manufacturing ,silicon carbide fiber.

Advantages
(1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.

(2) Good hardness, longer life.

(3) Chemical washed and water washed good cleanness.

(4) Special treated products get higher purity, better toughness, and better grinding effect.
