Silicon carbide is a class of wonder ceramics with high melting point (2730 °C), low density (3.21 g/cm3), excellent mechanical strength (>400 MPa) and elastic modulus (>400 GPa), and chemical inertness. SiC’s high decomposition temperature of 2830 °C, and relatively high thermal conductivity (k = 0.25 W/cm°C @ 200 °C) and low coefficient of thermal expansion (3.8x10-6 m/m-K @ 200 °C) are additional advantages for their use in several applications.
