Characterization of Ni0.5Zn0.5Fe2O4 Ferrite Synthesized by Solution Combustion method in the Presence of Urea and Glycine as fuels

Ni0.5Zn0.5Fe2O4ferrite, was produced by solution combustion synthesis method. In this way, by heating a solution containing an oxidizer and fuel, highly exothermic reaction occurs that results in the production of powder products with the desired compound. Powders produced in three various ratios of the fuel and oxidizer and 1 different modes of fuels (urea, glycine and combinations of these two fuels) were prepared and compared with each other. The maximum combustion temperature occurred in a sample of F/O=1. Based on the results of the XRD analysis, in all samples, spinel ferrite phase crystallized. FESEM photos shows that the type and amount of fuel has a significant impact on morphology and porosity of produced spinel ferrite. According to magnetic measurements, maximum saturation magnetization were obtained in F/O=1.4 and urea which were 67.22 emu/g. Also, all samples have narrow hysteresis loops, which indicates their soft magnetic properties.
