用化学共沉淀法制备了Ｙ２Ｏ３含量不同的两种Ｙ－ＴＺＰ纳米粉体；采用不同压力下冷等静压成形制备素坯；研究Ｙ２Ｏ３含量、素坯成型压力及烧结温度对Ｙ－ＴＺＰ陶瓷体密度、组织结构及机械性能的影响。
Two kinds of Y-TZP nano-powders with different content of Y2O3 were prepared by chemical coprecipitation method. The cold-isostatic pressing was used to prepare the blank. The effect of Y2O3 content, Density, structure and mechanical properties of the impact.
