Silicon Carbide Due To Chemical Stability
May 11, 2017

Silicon  carbide due to chemical stability, high thermal conductivity, thermal  expansion coefficient is small, good wear resistance, in addition to  abrasive, there are many other uses, such as: a special process to apply  silicon carbide powder turbine or cylinder The inner wall,  can improve its wear resistance and extend the service life of 1 to 2  times; used to make high-grade refractory, heat shock, small size, light  weight and high strength, energy saving effect. Low grade  silicon carbide (containing about 85% SiC) is an excellent deoxidizer  that accelerates steelmaking and facilitates the control of chemical  composition and improves the quality of the steel. In addition, silicon carbide is also used in large quantities for the production of silicon carbide rods.
The  hardness of silicon carbide is very large, Mohs hardness of 9.5, second  only to the world's hardest diamond (10), with excellent thermal  conductivity, is a semiconductor, high temperature can be antioxidant.
