Black cilicon carbide consists of crystalline silicon carbide,which is produced from silica sand and petroleum coke in electric resistance furnaces at temperatures of >2300℃.Siliconcarbide is iron-free,angular and extremely hard.

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.
