Abstract

In the La_1-xBa_xInO_3-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., La_0.6Ba _0.4InO_3-δ, was analyzed to be a single phase of a simple cubic. Under a dry atmosphere, La_0.6Ba_0.4InO _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.
