摘要
在Ａｌ_２Ｏ_３纳米粉中加入１００～４００ｍｇｇ^（－１）的０．０２５ｍｏｌＹ_２Ｏ_３－ＺｒＯ_２（Ｙ—ＰＳＺ），探讨了加入量对Ａｌ_２Ｏ_３纳米粉的烧结特性和烧成陶瓷力学性能的影响结果表明，Ｙ—ＰＳＺ可促进烧结致密化，降低烧结温度，并且有效地抑制烧结时Ａｌ_２Ｏ_３晶粒的长大，提高烧成陶瓷的性能．
The influences of Y-PSZ content on densification and mechanical properties of Y-PSZ containing A12O3 prepared with nanopowder have been investigated.It is shown that additing Y-PSZ to A12O3promotes densification of A12O3 and decreases sintering temperature.The Y-PSZ inclusions also significantly inhibite grain growth of A12O3 which resulted in the improvements in both hardness and toughness of Al2O3(Y-PSZ).
