摘　　要：简单介绍了氮化硅陶瓷的性质,其中通过加入第二相晶种或者自增韧形成的含有定向生长颗粒的氮化硅陶瓷具有优良的力学和热学性能,可以克服传统氮化硅陶瓷的脆性。同时介绍了制备这种陶瓷的加工工艺和国内外的研究现状。The property of silicon nitride ceramics are intriduced in this paper. Of all silicin nityide ceramics, the silicon nitride ceramics with aligned growed grains could overcome the brittleness traditional silicon nitride ceramics, which are realized by adding the second phase and in situ reinforcement, and which are prepared by using processing technics, such as tape casting and hot pressue sintering. They exhibit special mechanical and thermal properties. Meanwhile,the processing methods making the silicon nitride ceramics are presented and the progress at home and abroad is investigated.
