Microwave Synthesis and Characterizations of Ni_0.5Zn_0.5Fe₂O₄ Ferrite Powder

Abstract:

Microwave heating method was used to synthesize (Ni_0.5Zn_0.5)Fe₂O₄ ferrite from a stoichiometric mixture of corresponding metal oxides powders. The structural, chemical and magnetic properties of Ni-Zn ferrite was determined by X-ray powder diffraction (XRD) and vibrating sample magnetometry (VSM). Results showed that the material was spinel structure with a high purity with an estimated crystallite size of ∼30nm by X-ray line profile fitting. The sample systhetized by microwave energy at 860°C for 30min has magnetic properties of intrinsic coercivity 55.94G and saturation magnetization 19.43 emu/g. Compared with conventional burning method, microwave systhesis of NiZn ferrite is more efficient and reducing a lots of soaking time.
