company news about Properties and applications of silicon carbide

Silicon carbide was the hardest synthetic material known until the invention of boron carbide in 1929. It has a Mohs hardness rating of 9, close to diamond. In addition to hardness, SIC crystals have fracture properties that make them useful in grinding wheels, sandpaper, and cloth products. Silicon carbide has high thermal conductivity, high temperature strength, low thermal expansion, and resistance to chemical reactions, making it valuable in the manufacture of high temperature bricks and other refractory materials. It is also classified as a semiconductor, having electrical conductivity between metal and insulating materials. This, combined with its thermal properties, makes SiC a promising alternative to conventional semiconductors such as silicon in high-temperature applications.
