Abstract

Ultrafine barium hexaferrite BaFe12O19 powders were synthesized from the metallurgical extracts of lowgrade Egyptian barite ore via a coprecipitation route Hydrometallurgical treatment of barite ore was systematically studied to achieve the maximum dissolution efficiency of Fe ~997 under the optimum conditions The hexaferrite precursors were obtained by the coprecipitation of BaS produced by the reduction of barite ore with carbon at 1273 K and then dissolved in diluted HCl and FeCl3 solution at pH 10 using NaOH as a base the product was then annealed at 1273 K in an open atmosphere The effect of Fe3+/Ba2+ molar ratio and the addition of hydrogen peroxide H2O2 on the phase structure crystallite size morphology and magnetic properties were investigated by Xray diffraction scanning electron microscopy and vibrating sample magnetometry Singlephase BaFe12O19 powder was obtained at an Fe3+/Ba2+ molar ratio of 800 The formed powders exhibited a hexagonal plateletlike structure Good maximum magnetization 483 A·m2·kg–1 was achieved in the material prepared at an Fe3+/Ba2+ molar ratio of 80 in the presence of 5 H2O2 as an oxidizer and at 1273 K because of the formation of a uniform hexagonalshaped structure
