The present research aims of elaborating a new manufacturing technology of iron oxide nanoparticles. Composite Fe-C anode sputtering in a low-pressure arc discharge has been used to produce Fe-containing nanoparticles on a carbon matrix. The manufactured material was calcined in air up to 800 °C This procedure resulted in the formation of iron oxides and oxidation of carbon and its conversion into gas phase. The results show the changes in morphology, chemical composition, crystalline phases, and magnetic susceptibility properties with calcination temperature.
