Abstract
The Mn-Zn ferrites have been used in various technological areas, due to their attractive properties in technical and scientific senses. This paper aimed to synthesize Mn0.65Zn0.35Fe2O4 ferrites by combustion reaction and evaluate the effect of dilution of the reactants in distilled water on the microstructural and magnetic characteristics. The samples were characterized by X-ray diffraction, scanning and transmission electron microscopy, Curie temperature and magnetic measurements. It was observed that increasing dilution with water during synthesis by combustion reaction was favorable for obtaining monophasic Mn0.65Zn0.35Fe2O4 ferrite. It also favored a decrease in the agglomerate size and an increase in Curie temperature with maximum value of saturation magnetization of 62 emu/g for the sample diluted in 1:10 ratio.
