Material Characteristics Of Silicon Carbide

Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance, silicon carbide has many other uses besides being used as an abrasive. For example, coating silicon carbide powder on the inner wall of a water turbine impeller or cylinder body through a special process can improve its wear resistance and extend its service life by 1-2 times; The advanced refractory material used to make it is heat-resistant, small in size, light in weight, and high in strength, with good energy-saving effects. Low grade silicon carbide (containing about 85% SiC) is an excellent Oxygen scavenger, which can speed up steelmaking, control chemical composition and improve steel quality. In addition, silicon carbide is also widely used in the production of silicon carbide rods for electric heating components.
The hardness of silicon carbide is very high. The Mohs scale hardness is 9.5, second only to the world's hardest diamond (Grade 10). It has excellent thermal conductivity and is a semiconductor that can resist oxidation at high temperatures.
