Abstract
A modified route for synthesizing barium hexaferrite (Ba0.6Fe20a)
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 of O.OOSM-O.SM. The average particle size
of these coprecipitates ranged from 20 A to 170 A. Ferritization
studies have been carried out between 850° and 1150ac. The optimum
specific magnetic moments and coercive fields were in the range of
49-53 emujgm and 3.45-3.55 K Oe respectively.
