Synthesis of Mn Zn Ferrites by Oxide and Wet Chemical Methods

Vikas J. Pissurlekar ^[6]

Abstract: Mn Zn ferrite nanoparticles have been synthesized by taking two different starting chemical compounds, oxides as solid material and metal salts in solution by precursor method using hydrazine oxalate ligand by auto combustion self decomposition technique. The ferrites obtained from oxides and the metal salts were separately studied for their crystallite size, microstructure and magnetic properties using X-ray diffraction (XRD), scanning electron microscopy (SEM) and pulse field magnetic hysteresis loop tracer methods. The results showed that single phase ferrite could be achieved directly without any post calcinations. However, the crystallite size of the oxide auto combusted sample (24nm) was finer than that of the wet chemical method (43nm). The wet chemical synthesized Mn Zn ferrite with the larger crystallite size exhibited the larger magnetization of 53.4 emu/g than that of 39.6 emu/g for the oxide nanoparticles.
