| 摘 要： | 研究第二相粒子的引入对氮化硅陶瓷材料性能和显微结构的影响，结果发现：ＴｉＮ粒子的引入；对材料能起到协同增韧的作用，而ＴｉＢ２粒子由于与氮化硅颗粒表面的ＳｉＯ２发生反应，导致复合材料不致密，引起力学性能下降。

| Abstract: | Introducing the second phase particles, the effect of the second phase particles on the properties and microstructure of Si 3N 4 based ceramics was studied. It is shown that TiN particle can toughen and reinforce the matrix material and TiB 2 particles react with SiO 2 on the Si 3N 4 grain surface, so matrix material is not densified, leading degradation of properties. |

| Keywords: | second phase particle solution reaction toughen and reinforce |
