DESCRIPTION
Black silicon carbide powder is an abrasive material that is produced by the high-temperature smelting of quartz sand, petroleum coke, and other raw materials in an electric resistance furnace. The resulting product is then crushed, sieved, and purified to produce a high-quality, high-hardness abrasive powder. Black silicon carbide powder is characterized by its high hardness, low expansion coefficient, and excellent thermal conductivity, making it suitable for a wide range of industrial applications, including abrasive blasting, cutting, grinding, and polishing of various materials.
