black silicon carbide powder P280

Black silicon carbide powder is produced by smelting quartz sand and petroleum coke inside high‑temperature resistance furnaces. Featuring Mohs hardness of 9.2, good thermal conductivity, moderate electrical conductivity, excellent wear resistance and great chemical stability against acids and alkalis, this cost‑effective SiC material serves numerous industrial sectors across abrasive processing, thermal management, refractory metallurgy and advanced composite manufacturing.
Its most traditional and largest‑volume application lies in the abrasive and surface‑treatment industry. Graded black silicon carbide grits and micro‑powders are widely made into grinding wheels, abrasive belts, sandpapers and polishing pastes. It performs outstandingly for grinding cast iron, non‑ferrous metals such as aluminum, copper and brass, stone, marble, glass and low‑tensile‑strength non‑metallic workpieces. In sandblasting and water‑jet cutting operations, sharp‑edged black SiC particles efficiently remove rust, oxide scale, burrs and old coatings, achieving uniform matte surface finishing for machinery parts, casting components and hardware workpieces.
