Perovskite type SrCo0.4Fe0.6O3-delta (SCF) membrane and a novel perovskite-related ZrO2 doped SrCo0.4Fe0.6O3-delta(SCFZ) membrane were successfully prepared by isostatic pressing. The sintered membranes were characterized by high-temperature X-ray diffraction (HTXRD) and energy dispersive spectroscopy (EDS). The oxygen permeabilities of membranes have been measured in the temperature range of 923 K to 1243 K. The oxygen permeation flux at 1123 K and activation energy of SCFZ membrane with the thickness of 2 mm are respectively 2.68 x 10(-7) mol cm(-2) min(-1) and 91.76 kJ.mol(-1). The results of HTXRD in argon atmosphere and the oxygen permeation experiment indicate that the SCFZ membrane is stable at elevated temperature and low oxygen partial pressure.
