Abstract
In order to protect carbon/carbon (C/C) composites from oxidation, a silicon carbide coating had been produced by carbonizing rice hull though pack cementation technique. The component and morphology of the coating were analyzed by XRD, SEM and EDS methods. The results revealed that the coating with net structure was mainly β-SiC crystals and a few α-SiC crystals. The SiC coating with net structure could be produced at low temperature was due to nanometer crystallite of SiO2 in the carbonizing rice hull.
