The Preparation and Investigation of Magnetic Properties of Magnesium Zinc ferrites

Abstract

Mg 0.7 Zn 0.3 Fe 2 O 4 (MZF) is a ferrites material, displaying interesting magnetic properties. It has a wide range of magnetic coils and electronic devices. In this research, MZF ceramics was prepared by solid state reaction route and interested on sintering temperature that have effective on phase formation of MZF, microstruce and magnetic properties. The phase identification of ceramic ferrites was performed using X-ray diffraction technique (XRD). It has been found that the dense of MZF ceramics were successfully obtained for sintering at 1300 o C. Moreover, the microstructure of MZF ceramics were examined by scanning electron microscopy (SEM) and showed that the sizes of grain from 0.65-19.87 µm. The highly dense of MZF ceramics were obtained the magnetic permeability medium (µ) as 14.38×10 -14 N/A 2 .

Mg−Zn and Mn−Zn Ferrites Derived from Coil Core Materials as New Precursors for Catalysts of Primary Alcohols Transformations

“…The diffraction pattern of Mg−Zn ferrite (Figure a) shows the formation of pure nonstoichiometric cubic spinel phase with Fd 3 m (No. 227) structure . All the main peaks fit well with those of the spinel structure.…”
