Silicon carbide black sand F070 F080 Glass grinding abrasive grit
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. 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.
