Black silicon carbide has metallic luster and contains more than 95% SiC. It is stronger than green silicon carbide but has lower hardness. It is mainly used for grinding cast iron and non-metallic materials. The molecular formula is SiC. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum. It can be used as an abrasive and some other industrial materials. Silicon carbide for industrial use was successfully developed in 1891 and was the earliest artificial abrasive. Although a small amount of silicon carbide exists in meteorites and the earth's crust, no mineable mineral source has been found so far. Black silicon carbide contains about 98.5% SiC, and its toughness is higher than green silicon carbide. It is mostly used to process materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.
Silicon carbide has stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and good wear resistance. In addition to being used as an abrasive, silicon carbide has many other uses. For example, silicon carbide powder is coated on turbine impellers or cylinder blocks using special processes. The inner wall can improve its wear resistance and extend the service life by 1 to 2 times; the refractory material made of it is thermal shock resistant, small in size, light in weight, high in strength, and has good energy saving effect. Low-grade silicon carbide (containing about 85% SiC) is a better deoxidizer. It can speed up steelmaking, facilitate control of chemical composition, and improve the quality of steel.
