| 摘要 |
The invention relates to novel membranes, formed from perovskitic or multi-phase structures, with a chemically active coating which demonstrate exceptionally high rates of fluid flux. One application is the separation of oxygen from oxygen-containing feeds at elevated temperatures. The membranes are conductors of oxygen ions and electrons, and are substantially stable in air over the temperature range of 25.degree.C to the operating temperature of the membrane.
