| Abstract: | Chemical stability and cation stoichiometry determine the applicability of LaCrO3 as a high-temperature oxide electrode. A model for the behavior of acceptor-doped LaCrO3, as a function of oxygen activity is proposed. The model is in agreement with experimental data on Mg-doped LaCrO3. Stability regimes and compensation mechanisms at various oxygen activities and temperature are presented. |
