Abstract

An ethylenediamine tetraacetic acid (EDTA) precursor-based chemical method has been reported for preparation of single-phase barium hexaferrite nanopowder. Synthesized powders were characterized by thermogravimetric analysis, differential scanning calorimetric analysis, x-ray diffraction, particle size analysis, transmission electron microscopy, and scanning electron microscopy. DC electrical resistivity and magnetic properties of synthesized BaFe12O19 were measured by using a two-probe method and a vibrating sample magnetometer, respectively. This EDTA precursor-based method has the capability of producing nanostructured pure single-phase BaFe12O19 powder at a comparatively lower calcination temperature and offers the potential of a simpler, more cost-effective route than other reported methods.
