| 摘 要： | 以自制的纳米ＳｉＣ－Ｓｉ＿３Ｎ＿４复合粉体为原料，用气压烧结的方法制备陶瓷复合材料。对此材料用ＴＥＭ和ＨＲＥＭ电镜显微分析的结果发现两种不同的显微结构：纳米－微米结构和亚微米－微米结构。对两种结构的形成机理作了初步的探讨。

| Abstract: | SiC-Si_3N_4 composite ceramics was prepared by gas-press sintering, using nano SiC-Si_3N_4 compositepowder. Analysis of SiC-Si_3N_4 ceramics using TEM and HREM shows two different microstructtire: nano-micronstructure and submicron-micron structure. The formation mechanism of the two structures is discussed in this pa-per. |
