A process for manufacturing phase pure nanosized magneto-electric bismuth ferrite, involves synthesis of magneto-electric bismuth ferrite by soft chemical technique. The process is based on the formation of hetero-metallic poly-nuclear complexes where reacting metal atoms come in close proximity to provide nanosized bismuth ferrite at a low temperature. Bismuth ferrite synthesis through solutions of some specific salts leads to the formation of an amorphous structure at around 200°C which shows well-formed phase-pure (perovskite) nano-sized (15-25 nm) bismuth ferrite at 350-450°C. The process is a novel cost effective process and such nano-sized bismuth ferrite powder may have a potential application as a lead-free piezoelectric material for actuators, magneto-electric sensors and spintronics.
