Product Description
Black Silicon Carbide(SiC) is the product of silicon quartz sand and petroleum coke electro fused at high temperature in an electrical resistance furnace. The grains of Black Silicon Carbide are hexagonal crystals that are extremely hard, sharp, friable, and high strength(at 1000ºC, SiC is 7.5 stronger than Al2O3), and have outstanding electrical and thermal conductivity and low thermal expansion.
Application
Black Silicon Carbide-Sandblasting / Polishing / Lapping
Silicon Carbide is an extremely hard sharp grain that is more friable than aluminum oxide. Because it is so hard, Black Silicon Carbide requires less time than comparable media. Silicon Carbide is used in blasting of extremely hard materials. Silicon carbide comes in several sizes, ranging from coarse grit to fine powder, which is useful for polishing hard rock like granite. This abrasive is useful for grinding glass, removing mill scales and any other application where aggressive abrasives are required.
