摘　　要：本文研究了Ｙ２Ｏ３、ＭｇＯ含量对Ｙ、Ｍｇ－ＰＳＺ材料性能的影响。发现由于Ｙ２Ｏ３的加入、ＭｇＯ含量的提高可使Ｍｇ－ＰＳＺ的烧成温度由原来的１７００℃降低到１６００℃。与此同时材料的热稳定性也得到了较大的改善。Effects of Y 2O 3 and MgO contents on mechanical properties after 1100℃ aging and low temperature sintering of partially stablized zirconia were studied. The experimental results showed that, by using 14mol% MgO and adding 1～2.5mol% Y 2O 3, the sintering temperature was decreased to 1600℃ and the thermal stability with 1100℃ heat treatment was improved, as compared with 10MgO-ZrO 2 that had sintering temperature of 1700℃ and poor thermal stability at 1100℃
