摘　　要：氮化硅是一种具有优良性能的陶瓷材料,是一种理想的高温结构材料和高速切削刀具材料,近年来随着微波技术的发展,氮化硅的微波烧结越来越受关注。本文简述了氮化硅陶瓷材料传统烧结与微波烧结的研究现状;比较分析了各种烧结技术制备的氮化硅陶瓷的微观结构和力学性能,得出了微波烧结氮化硅陶瓷的优越性;最后提出氮化硅陶瓷微波烧结在未来研究中还需解决的问题。Silicon nitride is a kind of ceramic materials with excellent properties and it is an ideal material in the use of high temperature structures and high speed cutting tools. In recent years,silicon nitride sintered by microwave sintering has been attracted by more and more attention with the development of microwave technology. In the paper,the research status of silicon nitride ceramic materials sintered by conventional and microwave sintering was introduced. Microstructure and mechanical properties of silicon nitride fabricated by various sintering technologies were compared. The advantages of silicon nitride sintered by microwave sintering were concluded. Finally,several problems of microwave sintering of silicon nitride needed solved in the further research were proposed.
