英文摘要	the novel fe/nb co-substituted srco1-2x(fe,nb)(x)o3-delta (x=0.05, 0.10) oxides have been synthesized and characterized by x-ray diffraction (xrd), differential scanning calorimetry (dsc), thermogravimetry (tg), and scanning electron microscopy (sem). the xrd and dsc results demonstrate that the structural stability of the fe/nb co-substituted samples x=0.05, 0.10 is improved greatly compared to the sample x=0.00. the fe/nb co-doping in the srcoo3-delta oxide results in the improved structural stability of the srco1-2x(fe,nb)(x)o3-delta (x=0.05, 0.10) oxides. the nonstoichiometric and sintering properties were investigated by tg and sem, and the oxygen permeation fluxes were measured at 800-950 degrees c for the sample x=0.10. the improved oxygen permeability of the ceramic srco1-2x(fe,nb)(x)o3-delta (x=0.10) membrane compared to the (ba0.5sr0.5)(co0.8fe0.2)o3-delta and srco0.8fe0.2o3-delta membranes, was observed under an air/he oxygen partial pressure gradient at 800-950 degrees c.
