| 摘 要： | 给制了Ｓｉ－Ｃ－Ｏ－Ｎ系统平衡状态下相稳定性与Ｎ２分压和Ｏ２分压以及相稳定性与Ｎ２分压和ＳｉＯ分压的关系图；以此为指导，将原位复合引入到反应烧结锆莫来石（ＺＡＳ）材料中，制备了含原位（ｉｎ－ｓｉｔｕ）ＳｉＣ（ｐ）的ＺｒＯ２ＳｉＣ（ｐ）、ＺｒＯ２－３Ａｌ２Ｏ３·ＺＳｉＯ２－ＳｉＣ（ｐ）－ＳｉＣ（ｐ）复合材料。研究了烧结温度、时间、碳添加量、成型压力等工艺因素对烧结ＺｒＳｉＯ４－Ｃ体系中原位ＳｉＣ生成量的影响，并观察了试样的显微结构。

| Abstract: | The equilibrium phase in the Si-C-O-N syStem at 1773K and 1873K have been calculated and plotted as LogpN2 versus Logpo2 and logPN2 versus LogPSiO(g).Under the guidance of the predominance area diagrams plotted, ZrO2SiC(p) and ZrO2-3Al2O3.2SiO2(A3S2)-SiC(p) composites with in-situ SiC(p) were obtained by reaction-sintering method. COnditions for the formation of in-situ SiC(p) are presented with special emphasis on the reaction temperature, reaction time, C: ZrSiO4 molar ratio and forming pressure of samples.Observation on the microstructure of the samples has been made. |
