| Abstract: | Reaction sintered silicon carbide is a high-density,low-cost and net-shape forming material with excellent mechanical properties,corrosion resistance and oxidation resistance.However,free silicon often remains due to the special process of the reaction sintering method,seriously damaging its hot properties.The research status of the hot mechanical properties,the oxidation resistance,the thermal conductivity and the thermal shock resistance of the reaction sintered silicon carbide was expounded.The main measures to reduce the free silicon and to improve the mechanical properties in recent years were summarized,including the optimization of the preparation process as well as the introduction of the reinforcement and toughening phases.The future research direction of the reaction sintered silicon carbide was prospected. |
