摘　　要：以Y2O3为稳定剂,通过无压烧结制备了3mol%钇稳定氧化锆(3Y-TZP)陶瓷,研究了Y2O3不同加入方式、烧结温度对材料相变、显微结构和力学性能的影响。实验结果表明,Y2O3以化学法加入得到的材料中可相变四方相含量高,随温度升高材料致密化程度不断增加,1500℃烧结所得的材料具有最佳的力学性能。3Y-TZP ceramic was prepared by pressureless sintering using Y2O3 as stabilizer. The effect of the different ways of adding Y2O3 and sintering temperature on phase structure, microstructure and mechanical properties of the material were studied. The results showed that the content of t-ZrO2 was high when the Y2O3 was added by chemic technique and the densification increased with increasing sintering temperature. The material had the optimal mechanical property sintered at 1500℃.
