| Abstract: | The thermal shock resistance and the oxidation resistance of porous silicon carbide ceramics were investigated. The influence of different manufacturing processes on the thermal shock resistance and the oxidation resistance of porous silicon carbide ceramics were studied. The state change of SiO2 formed from SiC oxidation under different heat treatment temperature and their effects on the thermal shock resistance of the porous silicon carbide ceramics were also discussed. |
