| Abstract: | The overall resistance and resistances of the bulk and grain boundaries of solid electrolyte La0.8Sr0.12Ga0.82Mg0.18O2.85 kept for a long time in air at 773-1073 K are studied by impedance spectroscopy. The increase in the electrolyte resistance with time is shown to be connected with that in the resistance of grain boundaries. |
