摘要: Abstract The synthesis of bismuth ferrite by solid-state reaction Bi 2 O 3 and Fe results in the formation multiphase products. Even coprecipitation followed calcination leads to impurity phases. Here, we report magnetoelectric a ferrioxalate precursor method. In this process, ferrite, synthesized through solutions some specific salts led phase pure (perovskite) nanocrystalline powder (11–22 nm as evident from X-ray diffraction analysis) at temperature 600 °C. powders were characterized diffractometry, thermogravimetry differential thermal analysis, Fourier transformation infrared spectroscopy scanning electron microscopy. route is simple, energy saving cost-effective. Such nanosized may have potential application making lead free piezoelectric materials for actuators well sensors.
