Characteristics of silicon carbide

Since silicon carbide chemical stability, high thermal conductivity, thermal expansion coefficient, good wear resistance, except for the abrasive used, there are many other uses, such as: a special process the silicon carbide powder coating on the turbine impeller or cylinder body wall, can improve the wear resistance and extend the life of 1 to 2 times; for advanced refractory material, heat shock, small size, light in weight high strength, good energy saving effect. A low-grade silicon carbide (containing about 85% SiC) is an excellent deoxidizer, with its speed steel to accelerate and facilitate control of the chemical composition, to improve the quality of steel. In addition, silicon carbide heating element is also used extensively for the production of silicon carbide.
Silicon carbide's hardness great, Mohs hardness of 9.5, second only to the world's most hard-diamond (10), with excellent thermal conductivity, is a semiconductor, resistant to oxidation at high temperatures.
