In the La1-xBaxInO3-δ system, the compositions of x = 0.1-0.3 were analyzed to consist of cubic and orthorhombic structures. The composition of x = 0.4, viz., La0.6Ba 0.4InO3-δ, was analyzed to be a single phase of a simple cubic. Under a dry atmosphere, La0.6Ba0.4InO 3-δ exhibited a mixed conduction behavior of oxide ion and p-type electronic conductions at high oxygen partial pressures. However, in a nitrogen atmosphere, it showed pure oxide ion conduction. Proton conduction was observed in the presence of water vapor and the activation energy for proton conduction was measured as 0.84eV.
