摘 要：Stoichiometric Ni0.5Zn0.5Fe2O4 powders were produced by self-propagating high temperature synthesis （SHS）. The effects of NiCO3 content in the raw materials on the microstructure and magnetic properties of Ni-Zn ferrite powders were systematically studied. The Ni0.5Zn0.5Fe2O4 powders were characterized by X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The magnetic properties of the powders were evaluated by vibrating sample magnetometry （VSM）. The results show that the introduction of NiCO3 into reactants improves the con- version percentage and refines the Ni0.5Zn0.5Fe2O4 particles. The increase of NiCO3 content enhances the magnetic properties of Ni0.5Zn0.5Fe2O4. Particularly, the saturation magnetization reaches the maximum when the NiCO3 content is 3 at.%.
