Black Silicon carbide Grain is an extremely hard and 99% SiC carborundum grit. As an abrasive material, it can work well for abrasive blasting, surface treatment, grinding on hard material such as marble, glass, jade, etc. Silicon Carbide is produced by a process involving the electrochemical reaction of silica(SiO2)-in the form of quartz mixed with Carbon(C) in the form of raw petroleum coke.
