T1 - Structural stability and sintering properties of Fe/Nb/Ti co-substituted Sr(Co 0.8Fe 0.1Nb 0.1) 1-x Ti x O 3-δ (x = 0.00, 0.20, 0.40) oxides

N2 - The novel Fe/Nb/Ti co-substituted Sr(Co 0.8Fe 0.1Nb 0.1) 1-x Ti x O 3-δ (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(Co 0.8Fe 0.1Nb 0.1) 1-x Ti x O 3-δ (x = 0.20, 0.40) oxides is improved greatly compared with the sample x = 0.00 and the Ba 0.5Sr 0.5Co 0.8Fe 0.2O 3-δ oxide.
