- Abstract
In this study, an intermediate temperature ionic conductor, Ce0.95Eu0.05P2O7, was prepared by solid state reaction. The variation of conductivities with the pressure pH2O or time were studied. The highest conductivity of Ce0.95Eu0.05P2O7 sample was observed in dry air atmosphere at 300°C to be 1.1 x 10-4 S ⋅ cm-1 and in wet air atmosphere (pH2O = 7.4 x 103 Pa) at 100°C to be 1.4 x 10-3 S ⋅ cm-1, respectively. The log σ ~ log (pO2) plot result indicated that Ce0.95Eu0.05P2O7 was almost a pure ionic conductor under high oxygen partial pressure and a mixed conductor of ion and electron under low oxygen partial pressure.
