The phase formation and proton conduction in a BaO doped LaScO3 with the perovskite structure were studied.
La0.6Ba0.4ScO2.8 was analyzed as a single cubic phase and La0.9Ba0.1ScO3-d, La0.8Ba0.2ScO3-d and La0.7Ba0.3ScO3-d were analyzed

The phase formation and proton conduction in a BaO doped LaScO3 with the perovskite structure were studied.
La0.6Ba0.4ScO2.8 was analyzed as a single cubic phase and La0.9Ba0.1ScO3-d, La0.8Ba0.2ScO3-d and La0.7Ba0.3ScO3-d 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 La0.6Ba0.4ScO2.8 was higher than that of any other composition.
