Abstract : Magnetic nanoparticles based on Fe2O3 (Hematite) and Fe3O4 (Magnetite) are synthesized with an average diameter ranging from 30 nm to 45 nm using the Electric Arc Discharge Technique at a voltage of 70 V. These nanoparticles exhibit diverse applications in fields such as ferrofluids, magnetic refrigeration, catalysis, biomedicine, chemotherapy, magnetic hyperthermia, infertility treatments, cell isolation, medical diagnosis, magnetic gels, memory cards, memory chips, and various other biomedical applications. Worldwide, there is significant effort being directed toward developing simple, cost-effective methods for mass production of magnetic nanoparticles using electrolytes based on LiCl, KCl, and NaCl salts. This research focuses on the production of these nanoparticles, with the samples being characterized using techniques such as Vibrating Sample Magnetometry, X-Ray Diffraction, and Scanning Electron Microscopy.
