Abstract

Ferrite nanoparticles of basic composition Mg0.40,Cu0.25,Zn0.50Fe2O4 were synthesized through co-precipitation wet synthetic method by using oxalate as precursor at 90°C then filtered and washed with distilled water. After drying, heat treatment was carried out for 3 hours at 600°C and the resulting compounds were characterized for structural properties using X-ray diffraction [XRD], scanning electron microscopy, transmission electron microscopy, and Fourier transform infrared spectroscopy [FT-IR]. The XRD result shows that all prepared samples crystallite size are in the range of 30 nm to 60 nm and lattice constant in the range of 8.20 to 8.40 nm. Fourier Transform Infra Red Spectroscopy results clearly indicate the Mg-Cu-Zn nano Ferrite are synthesized. Differential scanning calorimeter graphs shows the phase formation of all the samples.

INTRODUCTION Ferrites or ferromagnetic oxides (also known as ceramics containing compounds of iron) are dark brown or gray in appearance and very hard and brittle in physical character. They are prepared by

It’s regarded that the fine particle morphology of the powder synthesized by this method is responsible for its higher sintering activity. The very fact that single phase ferrite could be obtained directly by citrate precursor without any additional heat-treatments above 750oC is a significant achievement considering the variety of applications of the Mg0.40,Cu0.25,Zn0.50Fe2O4. The highly active powders could be sintered at relatively low temperatures to obtain highly dense and homogeneous polycrystalline ferrites for high frequency
