摘要
采用拟抛物面规则预报了Ｏ′－ｓｉａｌｏｎ的标准生成Ｇｉｂｂｓ自由能．由无压烧结合成制备了Ｏ′－ｓｉａｌｏｎ－ＺｒＯ２－ＳｉＣ复合材料．分析了Ｏ′－ｓｉａｌｏｎ－ＺｒＯ２－ＳｉＣ材料烧结过程中物理化学变化．复合材料的抗折强度随ＳｉＣ含量增加而有所提高．复合材料中Ｏ′－ｓｉａｌｏｎ以柱状形式存在，且相互间构成编织状结构．
With the rules of quasi_paraboloid, the Gibbs energy of O ′-sialon was estimated. O ′-sialon-ZrO 2-SiC was synthesized by pressureless sintering, and thermodynamic analysis of reaction process is described. The fracture strength of composite increases with the addition of SiC; the columnar O ′-sialon forms an interwoven structure in the composite of O ′-sialon-ZrO 2-SiC.
