Abstract:
In the present study preparation and characterization of ferric oxide (Fe3O4) with ball milling has been done, for enhancing magnetic properties. Fe3O4 is obtained from the iron sands Sekotong Beach, West Lombok, Indonesia. The Fe3O4 has gained its importance due to its low cost, substitute for pure BaFe. Nano-sized Fe3O4 has applications in industrial fields such as ceramics, catalysts, energy storage, magnetic data storage, ferrofluids, as well as in medical diagnosis. Characterization of iron sand samples using Scanning Electron Microscopy with Energy Dispersive X-ray (SEM-EDX), and Permagraph Magnet Physik Germany, at BRIN LIPI Bandung. The result of characterization using SEM-EDX shows that iron sand samples contain Fe and O elements derived from Phase Magnetite (Fe3O4). The magnetic properties: Magnetic remanence (Mr), coersivity (Hc), maximum energy product (BH)) of magnetic, 3,01 kG, 4,97 kOe, 3,72 MGOe respectively. A small coercivity value is one of the characteristics of super paramagnetic materials.
