Abstract

Ceramics of the La0.88Sr0.12Ga0.82Mg0.18O3 − δ solid electrolyte was obtained by magnetic-pulse compaction (MPC) of a powder synthesized using the self-propagating high-temperature synthesis technique with further sintering at 1380°C. Conductivity and its change in time were studied. It was shown that conductivity of fresh samples coincides with conductivity of ceramics obtained using the classical solid-phase synthesis. It was established that conductivity of electrolyte decreased by 18% during isothermal exposure at 700°C for 1 year.
