Durable Metallurgical Grade Black Silicon Carbide Sic Lumps
Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance, silicon carbide has many other uses besides being used as abrasives. For example, silicon carbide powder is applied to the impeller or cylinder of a water turbine by a special process. The inner wall can increase its wear resistance and prolong its service life by 1 to2 times; the refractory material made of it has heat shock resistance, small size, light weight, high strength and good energy-saving effect. Low-grade silicon carbide (containing about 85% of SiC) is an excellent deoxidizer. It can speed up the steelmaking speed, and facilitate the control of chemical composition and improve the quality of steel. In addition, silicon carbide is also widely used to make silicon carbide rods for electric heating elements.
