Abstract: Aseries of non-stoichiometric compounds, Sr1-xBixFeO3-y of perovskite type were synthesized at 1100 ℃ and the chemical formula and the average valence state of iron ions were determined by chemical analysis.The structure and property of the compounds were characterized by X-ray powder diffraction, alternating current ohmage,IRand Mossbauer spectroscopy.The compounds have a Pm3m symmetry and show a semiconductor property.The iron ion in the compounds underwent disproportion reaction.The synthesis was obviously performed at lower temperature,shorter reaction time and lower energy consumption conditions compared to previous literature reports
Key words: Non-stoichiometric compound, Perovskite type compound, Semi-conductor, Disprototion reaction
