Perovskite type SrCo_(0.4)Fe_(o.6)O_(3-δ)(SCF) membrane and a novel perovskite-related ZrO_2 dopedSrCo_(o.4)Fe_(o.6)O_(a-δ)(SCFZ) membrane were successfully prepared by isostatic pressing.The sintered membraneswere characterized by high-temperature X-ray diffeaction (HTXRD) and energy dispersive spectroscopy (EDS).Theoxygen permeabilities of membranes have been measured in the temperature range of 923 K to 1243K.The oxygenpermeation fiux at 1l23K and activaion energy of SCFZ membrane with the thickness of 2mm are respectively2.68×10~(-7)mol.cm~(-2).min~(-1) and 97.76kJ.mol~(-1).The results of HTXRD in argon atmosphere and the oxygen per-meation experiment indicate that the SCFZ membrane is stable at elevated temperature and low oxygen partialpressure.
Perovskite type SrCo_ (0.4) Fe_ (o.6) O_ (3-δ) (SCF) membrane and a novel perovskite-related ZrO_2 dopedSrCo_ (o.4) Fe_ (o.6) O_ (a-δ) membrane were successfully prepared by isostatic pressing. The sintered porous membranes were characterized by high-temperature X-ray diffeaction (HTXRD) and energy dispersive spectroscopy (EDS). The oxygen perme permeabilities of membranes have been measured in the temperature range of 923 K to 1243 K. the oxygen permeation fiux at 1l23K and activaion energy of SCFZ membrane with the thickness of 2mm are respectively2.68 × 10 ~ (-7) mol.cm -2 (min -1) and 97.76kJ · mol -1 . The results of HTXRD in argon atmosphere and the oxygen per-meation experiment indicate that the the SCFZ membrane are stable at elevated temperature and low oxygen partial pressure.
