Abstract:The synthesis technology of AlON ceramics was investigated. The program of pattern recognition was used to optimize the parameters of AlON synthesis process, and the proper parameters were obtained by inverse projection. The thermodynamic properties of AlON were preliminary analyzed and estimated, phase stability diagrams at 2 073 K were calculated. AlON ceramics was synthesized by hot-press sintering under the conditions given by phase stabilitydiagram. The density of AlON is 3.63 g/cm3，about 97.8% of its theoretic density.
Key words: aluminum oxynitride; synthesis; pattern recognition
