The thermal stability of silicon carbide whiskers, which were grown by chemical vapor infiltration (CVI) method without any metallic catalyst, was analyzed. It was found that the thermal stability of the whiskers is one of the most important characteristics for applications in severe operation condition such as diesel particulate filters (DPF) of filters for incinerator and electronic power stations. The whiskers formed at over 1300°C were heavily faulted due to the rapid growth rate. It was observed that the stacking faults, as defects, reduce the activation energy for evaporation, so that evaporation occurred in spite of the relatively low temperature of annealing of 1100°C.
