Abstract
采用EDTA-柠檬酸联合络合法制备了(Ce 0.8 Y 0.2- x Nd x O 1.9 ) 0.99 (ZnO) 0.01 (0≤ x ≤0.2)系列电解质试样. 通过热重、X射线衍射、扫描电镜、热膨胀测试和交流阻抗谱等方法对试样进行分析, 着重研究了Y/Nd掺杂配比对CeO2基电解质材料电性能的影响. 结果表明: 采用EDTA-柠檬酸联合络合法制备的试样均为单一的立方萤石型结构; 添加1mol%的ZnO, 在1350℃下能得到较为致密的(Ce 0.8 Y 0.2- x Nd x O 1.9 ) 0.99 (ZnO) 0.01 系列电解质陶瓷片, 其中 (Ce 0.8 Y 0.05 Nd 0.15 O 1.9 ) 0.99 (ZnO) 0.01 电解质试样表现出最高的离子电导率, 其在750℃测试时的离子电导率为58.79 mS/cm; 所有试样的热膨胀系数在(11.83~12.30)×10 -6 /K之间.
