本工作针对中国原子能科学研究院氧化锆传感器多年来在现场使用中出现的问题,对固体电解质管、铂电极及其界面进行了较为系统的研究。对Y2O3稳定的ZrO2固体电解质(YSZ)、现场使用过的YSZ锆元件致密度、力学及电化学性能进行了测试分析。结果表明:YSZ锆元件晶粒尺寸和气孔率直接 In this work, a systematic study of the solid electrolyte tubes, platinum electrodes and their interfaces has been carried out in response to the problems that the zirconium oxide sensors of China Institute of Atomic Energy have encountered in the field over the years. The density, mechanical and electrochemical properties of Y2O3 stabilized ZrO2 solid electrolyte (YSZ), field-used YSZ zirconium components were tested and analyzed. The results show that: YSZ zirconium element grain size and porosity directly
