Abstract:
The 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 stepwise in air from 300 to 1100 K. This procedure resulted in the formation of Fe oxides and oxidation of carbon and converting it into gas phase. The results show the change in morphology, chemical composition, crystalline phases and magnetic susceptibility properties with annealing temperature. This research is directed to elaborate on new technologies for producing magnetic nanoparticles and ferrofluids from their basis.
