摘要

Barium ferrite is widely used as permanent magnets because of its large coercivity and low cost. The usual route to produce barium ferrites is the ceramic method. In order to overcome the detrimental milling effects in the magnetic properties, ferrite powders were obtained by coprecipitation. This method can produce high purity materials, i.e. particles composed of only BaO.6fp.e_2O_3. The effects of the PH during coprecipitation and calcination temperature in the magnetic properties were investigated. The molar ratio (Fe/Ba) used in this work was 10. The products were characterized by scanning electron microscopy and magnetic properties were evaluated by vibrating sample magnetometer. Particle size increases with decreasing PH and with increasing calcination temperature. Very fine particles were obtained. Intrinsic coercivities up to 4.80 kOe were achieved.
