The invention relates to a process for the production of oxygen using novel membranes, formed from perovskitic or multi-phase structures, with a chemically active coating which demonstrate exceptionally high rates of fluid flux. The process uses membranes that are conductors of oxygen ions and electrons, which are substantially stable in air over the temperature range of 25.degree. C. to the operating temperature of the membrane.
