Effects of calcination temperature on characterization of barium ferrite nanopowder produced via wet chemical route

This investigation dealt with the synthesis of nanocrystalline barium ferrite (BaFe12O19) powders through coprecipitationroute. The effects of calcination temperature on the phase composition and morphology of the sampleswere studied. X-ray diffraction results revealed that barium ferrite phase starts to form at calcination temperature of800˚C and fully formed when the temperature increased to 1000˚C. Field emission scanning electron microscopeanalysis showed that the prepared sample annealed at 900˚C contains barium ferrite plate-like particles with an averageparticle size of 60 nm. It was also observed that barium ferrite crystallites stack in side of each other due to theirmagnetic attraction.
