结果表明,氧浓差电池电动势的实测值与理论值吻合得很好,氧离子迁移数为1,表明该陶瓷样品在该温度下氧气气氛中为一纯氧离子导体;氧泵(氧的电化学透过)实验结果进一步证实了该样品在氧气气氛中为一纯氧离子导体;在氧分压p(O2)=10-5～105Pa的高氧分压气氛中,电导率与氧分压变化基本无关,表明在该氧分压范围内样品为纯离子导体,这与氧浓差电池电动势测定结果相吻合;在低氧分压为10-5～10-15Pa范围内,总电导率随氧分压降低而稍有升高,表明在该氧分压范围样品为氧离子与电子的混合导体;在600～1000℃下氧离子电导率>10-2S?cm-1,显著高于母体La2Mo2O9的氧离子电导率,1000℃时的氧离子电导率为0。
