| 摘 要： | 在氧化钇含量为8%(摩尔分数)的氧化锆中加入单斜氧化锆,1600℃常压烧结,制得不同含量的氧化钇稳定氧化锆.研究了不同含量的氧化钇对氧化锆陶瓷性能的影响,并对相组成及显微结构进行了分析.当氧化钇的摩尔分数为3%时,材料的相对密度、抗弯强度、硬度等综合力学性能同时达到最大值.超过这个临界点,材料力学性能又会逐渐下降.

| Abstract: | With adding m-ZrO2 to zirconia with 8mol% yttria,stabilized zirconia is prepared by sintering at 1600℃.The effect of the content of yttria on the mechanical properties of zirconia ceramic and the phase as well as microstructure of zirconia ceramic with different molar fraction yttria are studied.The results show that the best mechanical properties of ZrO2 stabilized by Y2O3 can be obtained when Y2O3 content is 3mol%.Over the critical content,the mechanical properties of zirconia ceramic gradually decrease. |
