Abstract

In this study, magnetic iron oxide nanoparticles were produced by thermal treatment of Fe(OH)3 colloidal solution after graphite arc discharge in the solution. The X-ray diffraction (XRD) pattern of the heat-treated powders showed that magnetic iron oxide nanoparticles (γ-Fe2O 3 or Fe3O4) were produced by the phase transformation from α-Fe2O2 at the thermal treatment temperature over 500 °C. The XRD pattern also indicated that the graphite powders produced by the arc discharge were contained in the Fe(OH)3 colloidal solution, suggesting that the graphite powders contributed to the reduction process of a-Fe2O3.
