Product Description
Black Silicon Carbide is mainly made of Quartz sand, petroleum coke, smelted by above2500°Cin the electric furnace. The hardness is between corundum and diamond. The Hardness is superior to corundum, it has the function of conductivity and thermal conductivity. It is suitable to process metals and non-metallic materials, such as gray cast iron, non-ferrous metal, stone, leather, rubber, and on on. It also widely used in refractories, metallurgic additives.
Because of the rarity of natural moissanite, most silicon carbide is synthetic. It is used as an abrasive, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 °C (2,910 °F) and 2,500 °C (4,530 °F). Fine SiO2 particles in plant material (e.g. rice husks) can be converted to SiC by heating in the excess carbon from the organic material. The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating with graphite at 1,500 °C (2,730 °F)
The green silicon carbide is produced by the same method as the black silicon carbide, but the raw material used requires higher purity, and is also formed at high temperature of about 2200 ° C in a resistance furnace, its SIC content is higher than that of black silicon carbide, and its physical properties are similar to that of black silicon carbide.

Product Application:
Application of Silicon Carbide powderHigh-grade refractory material; Special use material for polishing abrasive; Ceramic bearings; Ceramic engine parts; Grinding wheels; Textile ceramics; High-frequency ceramics; Hard disc and a support for multichip modules; High-temperature and high-power semiconductors; High-temperature ceramic bearings; High-temperature fluid transport parts; High hardness grinding materials; High-temperature sealing valves; High-temperature spray nozzles; Integrated circuit substrate; Catalyst support; Mirror or coatings for extreme ultraviolet environment; Nanocomposites (e.g., Si3N4/SiC, SiC/polymer); Resistance heating elements; Strengthening materials for Al, Al2O3, Mg, and Ni. Abrasive and cutting toolsIn the arts, silicon carbide is a popular abrasive in modern lapidary due to the durability and low cost of the material. In manufacturing, it is used for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting and sandblasting. Particles of silicon carbide are laminated to paper to create sandpapers and the grip tape on skateboards.Structural materialsilicon carbide is used in composite armor (e.g. Chobham armor), and in ceramic plates in bulletproof vests. Dragon Skin, which was produced by Pinnacle Armor, used disks of silicon carbide. Factory Photo
