分析了合成AlON的各种方法。 用模式识别结 合神经网络对碳热还原氮化合成AlON工艺 进行了优化, 利用模式逆映射得到了理想的合成工艺参数。 对AlON体系进行了热力学初步 分析, 计算了温度为2 073 K时合成AlON的热力学参数状态图。 根据热力学参数状态图所确定的条件, 热压合成了AlON陶瓷。 对所合成的AlON试样进行了 X 射线衍射标定及部分物理性能的测定。 其密度为3.63 g/cm3, 约为其理论 密度的97.8%。
The synthesis technolog y of AlON ceramics was investigated. The program o f pattern recognition was used to optimize the parameters of AlON synthesi s process, and the proper parameters were obtained by inverse projection. The th ermodynamic properties of AlON were preliminary analyzed and estimate d, phase stability diagrams at 2 073 K were calculated. A lON ceramics was synthesized by hot-press sintering under the conditions given by phase stability diagram. The density of AlON is 3.63 g/cm3, about 97.8% of its th eoretic d ensity.
