Abstract

The phase formation and proton conduction in a BaO doped LaScO₃ with the perovskite structure were studied. La_0.6Ba_0.4ScO_2.8 was analyzed as a single cubic phase and La_0.9Ba_0.1ScO_3.δ, La_0.8Ba_0.2ScO_3.δ and La_0.7Ba_0.3ScO_3.δ were analyzed to consist of two cubic and orthorhombic phases. Below 300°C, all compositions were found to be pure proton conductors in the presence of water vapor. The bulk conductivity of La_0.6Ba_0.4ScO_2.8 was higher than that of any other composition.
