Abstract
In order to reveal the oxygen diffusion through Ba0.95La0.05FeO3-(BLF), 18O2 vapor/solid exchange reaction were performed. Oxygen diffusion through BLF was observed by secondary ion mass spectrometry (SIMS). The relatively high oxygen diffusion and oxygen vacancy diffusion in BLF were estimated. From the diffusion data, it was found that the oxygen diffusion in BLF is attributed to the oxygen vacancy migration.
