Silicon Carbide SiC Material Properties

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.

Lattice thermal conductivity in cubic silicon carbide

01/11/2002· The lattice thermal conductivity of cubic silicon carbide is evaluated by means of a microscopic model considering the discrete nature of the lattice and its Brillouin zone for phonon dispersions and stering mechanisms. The phonon Boltzmann equation is solved iteratively, with the three-phonon normal and umklapp collisions rigorously treated, avoiding relaxation-time approximations.
