摘要：

Strontium ferrite (SrFe12O19) was synthesised in a solid phase reaction by applying the conventional ceramic method. The precursor powder, containing magnetic iron species generated by the electrocoagulation technique, was allowed to react with strontium carbonate in the solid phase. The molar ratio of the precursor to strontium carbonate was maintained at 12:1 (Fe:Sr), yielding strontium ferrite (SrFe12O19). The electrocoagulation sludge generated was characterised by X-ray diffraction, scanning electron microscopy and vibrating sample magnetometry. The strontium ferrite obtained was characterised by X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, thermogravimetric analysis, differential thermal analysis and vibrating sample magnetometry. The combined results of these analyses showed that the strontium ferrite obtained was of excellent quality with excellent magnetic properties.
