Synthesis of ultrafine particles of barium ferrite by chemical coprecipitation
A new method to synthesize barium hexaferrite by chemical coprecipitation is described. A mixed precursor was precipitated by addition of a barium salt to a strongly alkaline ferrate (VI) solution. The precursor yielded barium hexaferrite on heating for 6 h at 800°C; partial transformation was evide...
