Effect Of Milling Process On Particle Size, Morphology And Magnetization In Non-Stoichiometric Fe2o3-Mno2

A ratio non-stoichiometric between Iron oxide III and excess of Manganese oxide III were milled during 12 hours in a high energy ball milling using four iron spheres of diameter 12.7 mm and two iron spheres of diameter 9.5 mm. The characterization by X Ray Diffractions showed the phases of precursor powder in all samples, this result indicated that the powder only was milled and the process did not produce reaction. Rietvel refinement of X Ray Diffraction Patterns showed variations on crystalline planes and deformations occasioned by milling process, while Scanning Electron Microscopy and Particle Size Analysis showed that the particle size decreased with the process, a result in this study was the variation on magnetization without chemical reaction under non-stoichiometric conditions and the agglomeration sizes observed on samples. For the products have the same morphology by process.
