Synthesis and thermodynamic functions of barium cerate co-doped with erbium and indium

摘要

The new compound BaCe0.7Er0.2In0.1O2.85 was synthesized as a representative of promising class of solid state ionic conductors. Thermodynamic functions needed to improve and extend devices portfolio with a special emphasis on the heat capacity and phase transition have been revealed. It has been experimentally established that there is no phase transition for BaCe0.7Er0.2In0.1O2.85 in the temperature range of 191-695 K, which can give advantage to the practical application of this compound in comparison with materials possessing the phase transitions.
