Spinel-like ferrites has attracted attention due to its magnetic properties with the possibility of spintronic and magnetic memory devices applications as well as catalysis applications. This work aims to synthesize aluminum and iron spinel (FeAl2O4) by combustion reaction synthesis method and evaluate its structural and morphological characteristics, as well as its magnetic properties due to its wide application possibilities. The synthesis of this material was made using concentrated solutions of hydrated iron and aluminum metal nitrates, varying the type and quantity of fuel in order to verify its influence on the product microstructure. The fuels used in this work were urea and citric acid, both in stoichiometric quantity, said ideal, calculated from the chemical theory of propellants, and reactions with quantities above and below ideal. A synthesis using only metal nitrates without fuel was made for comparison. The final product of the different syntheses were characterized in terms of structure and composition by Xray diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Magnetic properties were obtained by vibrating sample magnetometry and the iron phase identification by Mössbauer spectroscopy. The analysis indicated that the sample synthetized without fuel corresponds to iron and aluminum oxides, mostly amorphous, with formation of nanometer hematite particles (Fe2O3) and a paramagnetic behavior. The characterizations of the samples produced with urea show higher crystallinity than the synthesized without fuel, with the sample in stoichiometric amount of urea, resulting in a single phase product identified as FeAl2O4 mixed spinel. The samples with excess and deficiency of urea had as product, besides the formation of the desired spinel, the formation of another phase identified as magnetite (Fe3O4), being all the samples synthesized with urea manifesting ferromagnetic behavior. The samples synthesized with citric acid, under all conditions, presented a triphasic system consisting of spinel, magnetite and hematite and showed also ferromagnetic behavior. In this work it is shown that combustion reaction synthesis was efficient to produce FeAl2O4, achieving better results using urea as fuel, in ideal quantity.
