High Hardness Black Silicon Carbide Mesh Powder Carborundum Grit
Silicon Carbide
The black silicon carbide is in black, with high hardness, strong cutting ability, stable chemical property and good thermal conductivity. And it can be divided into two types by different sizes:

Application of Silicon Carbide
Silicon carbide is with stable chemical properties, high thermal conductivity, low thermal expansion coefficient and good wear resistance, which can be used as abrasive. In addition, it can be widely used in many fields such as: coating silicon carbide powder on the inner wall of turbine impeller or cylinder block with special technology can improve its wear resistance and prolong its service life by 1-2 times; high-grade refractory materials used for making, thermal shock resistance, small size, light weight and high strength, and good energy-saving effect.
Low grade silicon carbide (containing about 85% SiC) is an excellent deoxidizer. It can accelerate steelmaking speed, control chemical composition and improve the quality of steel.
In addition, silicon carbide is also widely used in the manufacture of silicon-carbon rods for electrothermal components.
Silicon carbide is a semiconductor with high hardness and excellent thermal conductivity. It can resist oxidation at high temperature.
