Abstract

SrFe0.9Ti0.1O3-δ (SFT) was synthesized through glycine-nitrate combustion to elucidate its thermal decomposition behavior. In this work, dark precursor powders were obtained after combustion was completed. Thermogravimetric analysis (TGA) was conducted at room temperature to 1200 °C in static air with a heating rate of 10 °Cmin-1 for the as-prepared precursor powders. The total weight loss of 10.59% was obtained at temperature 1060 °C. The decomposition mechanism of perovskite oxide SFT was observed through Fourier transform infrared spectroscopy. X-ray diffraction (XRD) analysis confirmed the formation of cobalt-free SFT cathode with appearance of secondary phase Sr3Fe2O6 at 1100 °C. These results provide useful information to propose the calcination temperature of the synthesized powders.
