Studying the structural properties of Mg-Zn ferrite nano partical prepared by auto combustion Sol-gel method

Abstract

In the present work the Magnesium-zinc ferrite chain ( Mg_1-xZn_xFe₂O₄) with x=0-1,were synthesized using sol-gel auto combustion as a modern chemical ‎methods .Nitrates, citric acid and ammonia were used ‎in order to get ferrite nano powders at temperature 220⁰C , which characterized a higher dispersion ‎and homogeneity with particle size in the range of (27.47-68.9) nm. The obtained ferrite nano powder calcined at temperature  500⁰C for a period three hours .

Samples examined by Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). From FTIR spectral analysis the structure of the spinel ferrites shows two absorption bands,  , due to vibration of octahedral and tetrahedral metal oxygen bonds.  SEM results show the presence of uniformly distributed and almost spherical shaped particles.
