Black Silicon Carbide

Sandblasting material

Black silicon carbide is a sharp, hard synthetic abrasive made by the high-temperature fusion of silica sand and petroleum coke in an electric resistance furnace. With a Mohs hardness of 9.2 and a high thermal conductivity, it delivers fast cutting action, minimal heat generation, and excellent performance in grinding, cutting, and blasting applications. Its high purity and brittle nature make it ideal for precision machining of hard and brittle materials.

Features

Extremely hard (Mohs 9.2) for high cutting efficiency
Sharp, angular grain structure for aggressive material removal
High thermal conductivity for reduced heat buildup
Brittle nature enables constant self-sharpening edges
Chemical resistance to acids and alkalis

Applications

Grinding of ceramics, glass, stone, and non-ferrous metals
Abrasive blasting for hardened surfaces and coatings removal
Refractory production for high-temperature furnaces
Cutting tools and bonded abrasive wheels
Lapping and polishing of hard, brittle materials
