Abstract:The permanent magnet calcium strontium ferrite production as raw materials, W ferrite BaCoZnFe16O27 added in a ball milling. Preparation of W ferrite doped M type calcium strontium ferrite magnets with ceramic method. By X- ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and TPS—2000H type automatic measurement device of magnetic materials, the effects of morphology and magnetic properties of W ferrite materials were studied. The results show that the doping amount of carbonate can obviously improve the magnetic properties of M type calcium strontium ferrite, in doped 0. 5% (mass fraction), the sintering temperature of 1190℃, the magnetic energy of Br=455. 2mT, Hcb=330kA/m, Hcj=350kA/m, (BH)max=41kJ/m3。
