Sintered SIC
Sintered SIC (SSIC), formed from sub-micron powder, are sintered at temperatures in excess of 2000°C resulting in a fine-grain silicon carbide component that is extremely pure with nearly zero porosity. As a result, silicon carbide also has very high strength properties and can operate in oxidizing and corrosive atmospheres. Also, due to its extreme hardness, it is an excellent material for abrasive wear applications. In addition, silicon carbide has a high thermal conductivity and a low coefficient of thermal expansion, making it dimensionally stable across all temperature ranges.
