摘要
应用固体与分子经验电子理论(EET理论)计算了不同Y2O3掺杂量的ZrO2基固体电解质材料价电子结构,探讨了成分、价电子结构与离子电导率间的关系,得到了与实验规律一致的结果。提出了可用复合参量P来预测离子电导率,为从理论上预测具有高离子导电性的YSZ材料成分提供依据。
The valence electron structures of Y3+ doped ZrO2 electrolytes with different compositions were calculated by using the empirical electron theory(EET) of solids and molecules.The relationship between compositions,valence electron structures and ionic conductivities were also dealt with.The results of theory calculation are in accord with the experiment results.A complex parameter "P" is put forward to forecast conductivity in order to provide guide for selection of electrolytes with higher conductivities.
