摘要：
The novel Fe/Nb/Ti co-substituted Sr(Co0.8Fe0.1Nb0.1)(1-x) Ti (x) O3-delta (x = 0.00, 0.20, 0.40) oxides have been synthesized by the solid-state reaction method. These co-substituted strontium cobaltates possess a cubic perovskite-type structure at room temperature. Structural stability and sintering properties of the samples x = 0.00, 0.20, 0.40 were investigated by X-ray diffraction (XRD), thermogravimetry (TG), and scanning electron microscopy. The combined TG and XRD results demonstrate that the structural and chemical stability of the Fe/Nb/Ti co-substituted Sr(Co0.8Fe0.1Nb0.1)(1-x) Ti (x) O3-delta (x = 0.20, 0.40) oxides is improved greatly compared with the sample x = 0.00 and the Ba0.5Sr0.5Co0.8Fe0.2O3-delta oxide.
