Black silicon carbide is a type of abrasive material that is made from a mixture of quartz sand, petroleum coke, and high-quality silica. Through high-temperature smelting, black silicon carbide is formed with medium hardness, sharpness, and brittleness. This abrasive material is commonly used in various industries, including metalworking, ceramics, and electronics. Its unique properties make it an ideal choice for tasks such as grinding, cutting and polishing. Black silicon carbide is also known for its durability and resistance to wear and tear. Overall, black silicon carbide is an essential material for many industrial processes that require the use of abrasive materials.
Silicon carbide's stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and excellent wear resistance make it a versatile material with many uses beyond its abrasive properties. When applied to the inner walls of turbine impellers or cylinder blocks using a unique process, silicon carbide powder boosts wear resistance, extending the service life of the parts by one to two times. It serves as a high-grade refractory material, boasting heat shock resistance, small volume, light weight, high strength, and excellent energy-saving properties. Low-grade silicon carbide, typically containing 85% SiC, is an effective deoxidizer that accelerates steelmaking, facilitates chemical composition control, and enhances steel quality. The material also finds practical use in producing silicon carbide rods for electric heating elements.
Silicon carbide, known for its exceptional thermal conductivity and remarkable hardness, is also recognized as a high-temperature resistant semiconductor capable of withstanding oxidation.
