Product name | Abrasive black silicon carbide/Carborundum |
Model No | 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 | Raw materials are of high quality: pure silicon carbide, guaranteeing the products’ good quality. Sharp knife-edge, having cutting function. Centralized and uniform particle size distribution Electrical conductivity Heat conductivity Chemical stability High thermal conductivity Low expansion coefficient Good abrasion-resistance
|
