Abstract

Oxygen permeation property of A-site partially substituted barium cobaltites, A′xBa1-xCo0.7Fe0.3 O3-δ (A′ = Ba, Pr, Gd, Dy, Y and Yb), were examined. Substitution of Ba by Dy, Y or Yb was found to stabilize cubic perovskite structure even when x remained as small as 0.05. As a result, oxygen permeation through the disks made of these oxides appeared at temperature lower than 500 °C, and reached fairly high levels at elevated temperature.
