Black Silicon Carbide Granules

Black Silicon Carbide Granules

Black Silicon carbide is an extremely hard carborundum, it is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke.

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 of up to 2500℃ 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.
