在分析、绘制Ｓｉ－Ｏ－Ｎ三维立体参数状态图基础上，采用纯原料合成了Ｏ’－Ｓｉａｌｏｎ－ＺｒＯ２－ＳｉＣ复合材料．对实验结果用ＸＲＤ、ＴＥＭ进行分析，验证热力学分析的可靠性．结果表明，Ｏ’－Ｓｉａ－ｌｏｎ－ＺｒＯ２－ＳｉＣ复合材料中，主晶相Ｏ’－Ｓｉａｌｏｎ彼此之间构成网络状结构，ＺｒＯ２和ＳｉＣ颗粒弥散于编织状结构的孔隙中，起强化作用 Based on the analysis and drawing of state diagram of Si-O-N three-dimensional parameters, the O-Sialon-ZrO2-SiC composites were synthesized using pure raw materials. The experimental results were analyzed by XRD and TEM to verify the reliability of thermodynamic analysis. The results show that the main crystal phase O’-Sialon forms a network structure in the O’-Sia-lon-ZrO2-SiC composite and the ZrO2 and SiC particles disperse in the pores of the braided structure to reinforce
