| Abstract Scope |
This work was carried out to investigate the effect of the manufacturing route and alloying substitutions on the properties of the Ba-M ferrite magnets. The work focused on the production of ferrite magnets via the ceramic processing method and the chemical co-precipitation method. The effect of substitutions and additions of PbO, CaO and Al2O3 were investigated as well. The ferrite samples produced by the ceramic route were calcined, milled to ~ 1 micrometer particle size before compaction and sintering at high temperature (1250oC), while those prepared by the co-precipitation method consisted of nano-sized particles which were calcined at 600oC and sintered at 1000oC. The microstructure and the magnetic properties were studied using the SEM, XRD, TEM and VSM techniques. The effect of processing route and the alloying substitutions on the microstructure and magnetic characteristics of magnets were determined and discussed on the basis of merits of each processing route. |
