Chemical properties of silicon carbide

Silicon carbide chemical performance is stable, high thermal conductivity, small thermal expansion coefficient, good wear resistance, in addition to being used as abrasive material, there are many other uses. For example, with special technology in the turbine impeller and cylinder wall coated with Guangxi silicon carbide powder, can improve wear resistance, extend the life of 1~2 times of the very good refractory material, heat resistance vibration, small volume, light weight, high strength, good energy saving effect. Low grade silicon carbide (containing SiC about 85%) is a particularly good deoxidizing agent, can speed up the speed of steel, control the chemical composition, improve the quality of steel. In addition, silicon carbide is also widely used in the production of heating element silicon carbon rod.

Silicon carbide hardness is high, Mohs hardness 9. Level 5 Extremely hard diamond (Level 10). It has excellent thermal conductivity, is a semiconductor, can resist oxidation at high temperatures.
