Black Silicon Carbide (SiC) – High-Performance Abrasive Material for Industrial Applications
Black Silicon Carbide (SiC)
Black Silicon Carbide (SiC) is a premium synthetic abrasive produced by smelting high-purity quartz sand and petroleum coke in an electric resistance furnace at temperatures exceeding 2,000°C. Known for its exceptional hardness, sharp cutting edges, and excellent thermal conductivity, Black Silicon Carbide is widely used in grinding, polishing, lapping, blasting, refractory applications, and precision surface finishing.
With consistent particle size distribution and outstanding wear resistance, our Black Silicon Carbide delivers reliable performance across a wide range of industrial processes.
