摘要: A modified route for synthesizing barium hexaferrite (BaO.6Fe2O3) through ammonium carbonate using metal chlorides is reported. The coprecipitations were studied in the range of pH 7.2–8, Fe/Ba ratio 8.55–11.5, and dilutions 0.005M–0.5M. average particle size these coprecipitates ranged from 20 to 170 A. Ferritization studies have been carried out between 850° 1150°C. optimum specific magnetic moments coercive fields 49–53 emu/gm 3.45–3.55 K Oe respectively.
