A new method for preparation of magnetite from iron oxyhydroxide or iron oxide and ferrous salt in aqueous solution

چکیده مقاله

In this study, a new method is proposed for the preparation of Fe3O4 from iron oxyhydroxides (goethite, akaganeite, lepidocrocite, feroxyhyte and ferrihydrite) or iron oxide (hematite) and ferrous salt in aqueous solution. The product is magnetite with various particle sizes. Products are characterized by X-ray powder diffraction, IR spectra and vibrating sample magnetometery
