Magnetic Submicron Powder Preparation and Characterization
The goal of this experimental study was to present a comparative analysis of iron oxides powders obtained by two alternative methods, i.e. the co-precipitation at high temperature from aqueous reaction medium of iron oxides and, respectively, the solvent free method for the preparation magnetite at room temperature. Vibrational absorption spectra evidenced the dominancy of magnetite in both samples, while the X-ray diffractograms revealed the submicron size as well as the presence of additional iron oxide, in the second sample prepared by solvent free method.
