Silicon Carbide Grits

Looking for a reliable Black Silicon Carbide supplier with stable quality and fast delivery?

We manufacture high-performance black silicon carbide (Black SiC / black carborundum) for refractory, steelmaking, abrasive, and ceramic applications. With advanced production lines and strict quality control, we ensure consistent chemical composition and particle size distribution for industrial use

Black silicon carbide is produced by smelting high-quality quartz sand and petroleum coke at high temperature. It features:

High hardness (Mohs 9.2–9.5)

Excellent wear resistance

Strong thermal conductivity

Good oxidation resistance

Stable chemical properties

Compared with green SiC, black SiC offers better toughness and more competitive pricing, making it ideal for large-scale industrial applications.
