Application:
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.
