Because black silicon carbide refractories refractories do not have other common characteristics, such as high thermal conductivity, low coefficient of expansion, excellent wear resistance and virtually no reaction with the slag and other characteristics, applications in this field more widely.

green silicon carbide chemical stability
high thermal conductivity, thermal expansion coefficient, good wear resistance, except for the abrasive used, there are many other uses, synthetic diamond such as: a special process the silicon carbide powder coating on the cylinder block of the turbine impeller or wall, can improve the wear resistance and extend the life of 1 to 2 times; for advanced refractory materials, heat shock, small size, light in weight high strength, good energy saving effect. A low-grade silicon carbide (containing about 85% SiC) CBN abrasive grit 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), has excellent thermal conductivity, is a semiconductor, resistant to oxidation at high temperatures.
