Black Silicon Carbide
They are black hexagona crystals with fragile and sharp properties,good heat and electricity conduction.Main purpose:
Manufacturing of bonded abrasive products and coated abrasive tools; grinding and polishing of stones; processing of
low-tensile strength metal and non-metal materials,including grey cast iron,brass,alumina,stones,leather,rubber,etc.
