What is Black Silicon Carbide?
Black Silicon Carbide, also known as Black SiC, is primarily composed of silicon and carbon. It is produced through the high-temperature fusion of quartz sand and petroleum coke in an electric resistance furnace.
The powder typically consists of small, sharp-edged particles with a crystalline structure. Black silicon carbide is renowned for its high hardness. This property makes it an excellent abrasive material, which is suitable for applications requiring effective material removal.
