Abstract

Mixed oxide-ion and electronic conductive thin films with the composition of (Ce_0.85Sm_0.15)O_2-δ-15 vol%MnFe ₂O₄ (CSO-MFO) were prepared on porous yttria stabrized zirconia substrates by a spin coating process, and their oxygen permeation flux densities were measured. The porous substrates were prepared from ZrO ₂-3 mol%Y₂O₃ (3YSZ)-33 vol%carbon and NiFe ₂O₄. 3YSZ porous substrates were obtained from 3YSZ-33 vol%carbon by sintering at 1350°C under Ar for 5 h and following oxidation at 800°C under air for 2 h. For 3YSZ-33 vol%NiFe₂O₄, the optimum condition was sintering at 1400°C under air for 5 h and following reduction at 800°C under H₂ for 2h. A CSO-MFO film was prepared by a spin coating process on the substrate. The thickness of the CSO-MFO was approximately 150 nm. Oxygen flux density of the CSO-MFO sample was found to be 8.9 × 10^-8 mol·cm^-2·s ^-1.
