The Preparation and Investigation of Magnetic Properties of Magnesium Zinc ferrites

A. Rittidech, N. Sinthorn and A. Noisaguan    

Abstract: Mg0.7Zn0.3Fe2O4 (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 oC. 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 (ยต) as 14.38x10-14 N/A2.
