摘　　要：碳化硅(SiC)木质陶瓷是一种新型陶瓷材料。采用液相渗硅工艺制备的SiC木质陶瓷具有优异的力学性能,在结构陶瓷方面具有潜在的应用前景。概述了SiC木质陶瓷的研究进展。本文重点论述了SiC木质陶瓷的制备工艺、组成与结构及力学性能。分析了SiC木质陶瓷组成与密度对力学性能的影响,并与传统反应烧结法制备的SiC陶瓷的力学性能进行了对比,最后指出了提高SiC木质陶瓷的力学性能所必需解决的问题。Silicon carbide （SIC） woodceramic is a new kind of ceramic materials. It has excellent mechanical properties and therefore potential application prospects in structural ceramics fabricated by the liquid silicon infiltration process. The research progress of the silicon carbide woodceramics is summarized. The fabrication process, composition and microstructure and mechanical properties, together with the influence of the composition and density of SiC woodceramic on the mechanical properties are discussed. Furthermore, the mechanical properties of SiC woodceramics and traditional SiC are compared. Finally, the existing problems that must be solved to enhance the mechanical properties of silicon carbide woodceramics are also pointed out.
