Abstract

PURPOSE:To obtain magnetic particles which are chemically stable, improved in magnetic characteristics and easy to turn into paint, by heating and drying needle particles produced through reduction of ferromagnetic metal ion solution with borohydride under non-oxydizing atmosphere and within a specific temperature range.
