Black Silicon Carbide Supplier
High Purity Black SiC Grain & Powder for Industrial Applications
Are you sourcing a reliable black silicon carbide supplier for refractory, steelmaking, or abrasive production?
We manufacture and export high-performance black silicon carbide (Black SiC / black carborundum) with stable purity, controlled particle size distribution, and consistent batch quality. Our products are widely used by steel plants, refractory manufacturers, foundries, and abrasive producers worldwide.
What Is Black Silicon Carbide?
Black silicon carbide is produced by smelting quartz sand and petroleum coke in high-temperature electric resistance furnaces. It is known for:
High hardness (Mohs 9.2–9.3)
Excellent abrasion resistance
Strong thermal conductivity
Good oxidation resistance
Stable chemical composition
Compared with alternative materials, black SiC offers a strong balance between performance and cost, making it ideal for large-volume industrial use.
