Influence of Bi203 on the structure and magnetic properties of barium ferrite powders materials
In this study,influence of Bi2O3 on the structure and magnetic properties of barium ferrites has been studied in samples performed by using the solid-state reaction method.Samples,prepared with different amount of sintering additive are sintered at temperatures from 850℃ to 950℃.The scanning electron microscope micrographs shows that the samples with 3wt% additive,calcinated at 900℃,have a particle size smaller than lμm.Annealing treatment in air at 950℃ led to an order-of-magnitude increase of the saturation magnetization of 60.42emu/g and coercive force of 4150.5Oe,which are due to the liquid phase sintering mechanism and the increasing grain size.
