Abstract
The structural and morphological properties of Mg- Fe- O system were determined by using X-ray diffraction (XRD), Scanning electron micrographs (SEM), Infrared (IR) and Energy dispersive X-ray (EDX) techniques. Combustion method resulted in formation Mg- Fe- O system in one step. The results revealed that the as prepared solids consisted entirely of well nano- crystalline spinel magnesium ferrite solid solution with iron-rich composition, MgFe2O4.xFe2O3, depending upon XRD data. SEM shows formation of nano- materials with sponge-like structure. The concentration of constituents, involved in the as synthesized material was determined by using EDX technique. In fact, it was found the concentration of Mg, Fe and O species changes from the uppermost surface layer to the bulk of the system studied.
