摘要: 采用湿化学法合成了Y2O3稳定的立方ZrO2微细粉料。利用热分析(DTA、TG和DSC)X射线衍射法和电子显微镜(TEM和SEM)等研究了立方ZrO2的形成过程和粉料的烧结行为。以交流阻抗谱技术测定了烧结试片的电导率,表明在低于750℃温度范围内电导率略高于文献值。还讨论了稳定化ZrO2的形成机理及电导率与温度的关系。

关键词: Y2O3稳定的ZrO2, 氧离子导体

Abstract: The fine powder of Y2O3 stabilized ZrO2 with fec structure was. synthesized by a wet chemical method. Thermal analysis techniques(DTA, TGand DSC),X-ray diffraction and electron microscope (TEMand SEM) etc. were applied to study the formation of fcc phase and the sintering behaviour of the powder. ACimpedance measurement showed that the sintered YSZsamples exhibited higher conductivity than that reported in literature in lower temperature range(<750℃) . The formation mechanism of YSZfcc phase and temperature dependance of conductivity were discussed.

Key words: Y2O3 stabilized ZrO2, Oxygen ionic conductor
