The thermal conductivity of SiC/SiC composites is strongly dependent on the processing conditions, type of fiber, and fiber architecture. The upper limit for thermal conductivity corresponds to that obtained in single crystal and high-purity CVD SiC, with maximum values of ~320 W/m-K at room temperature and 78 W/m-K at 1000ßC (Fig. 1).

Silicon carbide is a compound composed of silicon and carbon, with the chemical formula (SiC). It is a hard, brittle crystalline material with excellent thermal conductivity, high melting point, and resistance to chemical wear.
