Extensive efforts have been made to synthesize single phase and stoichiometric BiFeO3. Some modified techniques have been tried in synthesizing BiFeO3 as compared with the conventionally used co-precipitation method. Thermogravimetric Analysis/Differential Scanning Calorimetry and x-ray diffraction experiments were used exclusively to explore the effects of heat treatment temperature and time on crystallographic behavior of the prepared BiFeO3 powder. Field emission scanning electron microscopy was used to explore the microstructure of the synthesized BiFeO3. The appearance of different magnetic phases in 57Fe Mössbauer spectra and field dependent magnetization was confirmed on the basis of particle size distribution. In this research, an easy, low cost and high-yield method for the low temperature single phase and stoichiometric synthesis of BiFeO3 has been suggested.
