SiC (silicon carbide) is a compound semiconductor composed of silicon and carbide. SiC provides a nuer of advantages over silicon, including 10x the breakdown electric field strength, 3x the band gap, and enabling a wider range of p- and n-type control required for device construction.
Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800 C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength give this material exceptional thermal shock resistant qualities.
