Y2O3-MgO共稳定ZrO2的相研究
摘要
通过化学组成和相含量设计
采用湿混法制备了MgO和Y2O3共同稳定ZrO2粉末
在不同的温度下烧结
获得了室温下单斜相和四方相含量不同的烧结样品
用X射线峰宽化法测定并计算了粒子尺寸。结果表明:随着Y2O3含量的增加
单斜相含量降低
四方相含量增加。温度对相含量的影响较小
而晶粒尺寸受Y2O3和温度的影响并不明显。

-MgO powder is prepared by wet-mixing after designing the composition and phase content.Sintered sample which has different amount of monoclinic and tetragonal phase at room temperature is obtained at different sintering temperature.The grain size is investigated by X-ray pattern.The result shows that the content of monoclinic ZrO

is increased and the content of tetragonal ZrO

is decreased with the addition of Y

.The sintering temperature has little influence on the phase transformation.Meanwhile the sintering temperature and the Y

content have little influence upon the grain size.
