Black Silicon Carbide
Black silicon carbide is produced with petroleum coke, quartz sand and additives .
The powders are the perfect material that specifically manufactured to be used for general abrasive applications in bonded abrasive tools, lapping and polishing processes. It is widely used for grinding non-ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important.
