Abstract

Ce_0.8Gd_0.2O_1.9 (CGO) - MFe ₂O₄ (M=divalent cation) is a composite-type oxygen-ionic and electronic mixed conductor. Dense nanocrysalline CGO-CoFe₂O ₄ thin films with a thickness of approximately 1 μm were prepared on CGO porous substrates by a chemical solution spin-coating method. The oxygen permeable flux of the thin film was investigated in temperature range of 700°C - 800°C without physical leak of N₂ gas. The permeable flux depends on the measuring time, when the measuring temperature was kept at 750°C before increasing to 800°C. This fact suggests that the O ₂ permeable properties were affected by a slight change of the film morphology and the crystallinity.
