Abstract: Ferrimagnetic materials such as natural magnetite are used for practicalapplications because of their electronic, magnetic and catalytic properties inthe degradation of organic compounds. In order to determine its physicochemicalproperties in relation to its catalytic activity, the natural magnetite of Ofoud Mount (Niger) ischaracterized by X-ray florescence (XRF), X-ray diffraction (DRX), specificsurface area (BET) and Fourier transformed infrared (FTIR). The result shows aniron content of 97.09 and a specific surface area of 69.742 m2 g.The crystal structure of magnetite is cubic with lattice parameters α = β = γ = 90°, a (Å) = b (Å) = c (Å) =8.3740. The results of this study suggest that the natural magnetite of OfoudMount can be used as iron source in various fields of science despite thepresence of a few impurities that can improve its catalytic activity.
