Black Silicon carbide Grit

Black Silicon carbide Grit is an extremely hard and 99% SiC carborundum grain. As an abrasive material, it can work well for abrasive blasting, surface treatment, grinding on hard material such as marble, glass, jade, etc.

Black Silicon carbide Grit 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. The stoichiometric mixture is reacted in an electrical resistance furnace at a temperature up to 2500 centigrade to yield high-quality crystals. The process is large furnace technology with a graphite electrode in the furnace center.  The large crystals are then segregated, crushed, cleaned of magnetic impurities in high-intensity magnetic separators, and classified into narrow size fractions to suit the end-use. Dedicated lines produce products for different applications.
