BA-#20 

Brand name

CNBM

Description

• Black silicon carbide is produced in an electric-resistance type furnace through fusing quarts sand and petroleum coke and high quality silica with high temperature. Its hardness is between fused alumina and diamond's. 

• higher mechanical intensity than fused alumina's. 

• It is brittle and sharp and has electrical and heat conductivity in some degree. Black silicon carbide, metallic, sic≥95%, stronger than green silicon carbide but softer than green silicon carbide, is mainly used for grinding of cast iron and non-metallic materials.

Advantage

1. Raw materials are of high quality: pure silicon carbide, guaranteeing the products’ good quality.

2. Sharp knife-edge, having cutting function.

3. Centralized and uniform particle size distribution

4. Electrical conductivity

5. Heat conductivity

6. Chemical stability

7. High thermal conductivity

8. Low expansion coefficient

9. Good abrasion-resistance
