通过在Ｙ－ＴＺＰ中加入适量的硅酸盐玻璃添加剂，使其烧结温度明显降低，并且制备出具有细晶粒、高强度的四方相氧化锆增韧陶瓷材料．分析了添加剂含量及烧结温度与材料致密度、显微结构及力学性能的关系，发现在Ｙ－ＴＺＰ材料中加入１ｗｔ％的添加剂，可以使材料在１４００℃下烧结，氧化锆晶粒尺寸约为１００～２００ｎｍ；其抗折强度可达９５０ＭＰａ．
Tetragonal Zirconia Polycrystals (TZP) with superfine grains and high flexural strength were obtained by adding certain glass additives into Y-TZP powder and sintered at low temperature. The relationship between the density, mechanical properties arid the amount of additives, sintering temperature were investigated. The results show that Y-TZP with 1wt% glass additives can be densifed at 1400℃. The grain size of Y-TZP is 100-200nm and flexural strength can reach 950MPa.
