Abstract

The application of mixed ionic-electronic conducting oxides as oxygen separation membrane for the production of oxygen offers significant advantages over conventional cryogenic distillation. Perovskite- and fluorite-type oxides are promising candidates for such application. The research described in this thesis is mainly focused on i) crystal chemistry and phase stability of either Zr- or Nb-substituted Ba0.5Sr0.5Co0.8Fe0.2O3-¿ (BSCF), and those of the parent perovskite phase, and ii) oxygen surface exchange kinetics of selected perovskite- and fluorite-type oxides.
