Abstract

The diffusion profiles of 18O in La0.9Sr0.1FeO3 and La0.9Sr0.1CoO3 were measured with a secondary ion mass spectrometer. The gas-solid oxygen isotopic exchange reaction was strongly limited by a surface reaction. The depth profile data were carefully treated and the tracer diffusion coefficient of oxide ions in the oxides was determined successfully.
