Description

Black Silicon Carbide is made by a precision water classification process and air flow classification using material that is produced from the reaction between high purity silica sand and petroleum coke in a resistance-type furnace. Measuring 9.0+ on the MOHS scale of hardness, silicon carbide is one of the hardest abrasives known in the industry. The inherent friability of the sharp crystalline structure assures the continuous exposure of new cutting edges, which produces a faster and cleaner cutting performance.

Green silicon carbide is produced as the same type as the black silicon carbide, except the different raw materials. It’s crystallization have higher purity and hardness. Green silicon carbide is suitable for processing hard alloy, metallic and non-metallic material with hard and brittle feature such as copper, brass, aluminum, magnesium, jewel, optical glass, ceramics, etc. Super micro-power of it is also a kind of ceramics material.
