SILICON CARBIDE (SiC) - University of California, San Diego
SiC is known to have high intrinsic strength and stiffness (E = 450 GPa @ RT), high temperature stability (decomposition temperature is 2830 C) and excellent oxidation resistance. The relatively high thermal conductivity (k = 0.25 W/cm-C @ 200 C) and low coefficient of thermal expansion ([[alpha]] = 3.8x10 -6 m/m-K @ 200 C) result in favorable thermal shock resistance when compared to other
