Long life in hard use

Black Silicon Carbide is manufactured from high purity quartz and coke, and fused in a resistance furnace under controlled conditions for purity and crystalline structure. They are also used on paper, fiber, or cloth backing and with a glue or resin adhesive. The grain shape is designed to impart high projectability when electrostatically coated.
