| 摘 要： | 对作为析氧阳极的氧化锆固体电解质在带电和不带电条件下,于冰晶石熔盐中的腐蚀行为进行定性研究。采用高倍扫描电镜及能谱分析等手段,对氧化锆固体电解质在电解前后的表面及截面形貌进行观察及分析,探讨固体电解质在冰晶石熔盐中的腐蚀情况及腐蚀机理。研究结果表明：在不带电条件下,与普通的惰性阳极一样,氧化锆固体电解质在冰晶石熔盐中遭到严重腐蚀,而在通电条件下,氧化锆固体电解质由于在冰晶石熔盐中存在一定程度的化学溶解动力学阻碍而呈现出良好的耐腐蚀性能。

| Abstract: | The corrosion behavior of solid electrolyte used for the evolution of oxygen in molten cryolite salt was studied. The morphologies of the ZrO2-solid electrolyte were measured by scanning electron microscopy and EDS analysis. The results show that the solid electrolyte is eroded badly in the molten cryolite salt. However, the solid electrolyte has good corrosion-resistive ability to molten cryolite salt during the process of electrolysis. The solid electrolyte exhibits embarrassment of dissolution during the process of electrolysis. |
