This investigation dealt with the synthesis of nanocrystalline barium hexaferrite (BaFe 12 O 19 ) powders through the co-precipitation–calcination route. The ferrite precursors were obtained from aqueous mixtures of barium and ferric chlorides by co-precipitation of barium and iron ions using 5M sodium hydroxide solution at pH 10 in room temperature. These precursors were calcined...
