black silicon carbide chemical stability

Black silicon carbide and silicon carbide green silicon carbide two common basic varieties, Silicon carbide due to 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 cylinder block turbine impeller or wall, can improve the wear resistance and extend the life of 1 to 2 times;  black silicon carbide for advanced refractory material, heat shock, small size, light weight high strength, good energy saving effect. A low-grade silicon carbide (containing about 85% SiC) is an excellent oxygen scavenger, which can be used to accelerate the speed of the steel brown fused aluminum oxide  and to facilitate control of the chemical composition, to improve the quality of steel. In addition, silicon carbide heating elements are also used extensively for the production of silicon carbide.
The great hardness of silicon carbide having excellent thermal conductivity, is a semiconductor, is resistant to oxidation at high temperatures.
