Preparasi Nanopartikel Oksida Besi Berbasis Pasir Alam Logas Didoping Aluminium Menggunakan Metode Mechanical Milling

---

Iron oxide nanoparticles were prepared using a 4-stage mechanical ball milling method based on Logas natural sand for 200 hours and each stage was processed with NdFeB magnets to separate iron oxide and non-iron oxide particles. The final ball milling product was divided into 4 parts with equal weight. Aluminum with a Konsentration of (0, 1, 2, 3, 4) wt.% was doped into the iron oxide nanoparticles respectively and the products were called BM 5A, BM 5B, BM 5C, BM 5D, and BM 5E. The effect of aluminum doping Konsentration on magnetic properties, morphology, and composition was determined by Vibration Sample Magnetometer (VSM), Scanning Electron Microscope (SEM), and X-Ray Fluorescence (XRF), respectively. The magnetic properties in terms of saturation magnetization (Ms) showed a decrease with values of 22.22 emu/g, 20.22 emu/g, 19.41 emu/g, 19.39 emu/g, and 16.95 emu/g as the aluminum Konsentration increased. Coercivity (Hc) values varied from 121.52 Oe, 227.37 Oe, 253.05 Oe, 256.47 Oe, 244.54 Oe, and remanent magnetization (Mr) showed varying values ranging from 3.05 emu/g, 3.38 emu/g, 3.63 emu/g, 3.37 emu/g, and 3.14 emu/g as aluminum Konsentration increased. The average particle sizes of the samples were 733 nm, 557 nm, 697 nm, 719 nm, and 690 nm with increasing aluminum Konsentration by (0, 1, 2, 3, 4) wt.%, respectively. These values are greater than those of pure hematite. The composition of ball milling products doped with 2 wt.% aluminum yielded 34.278% Ti, Fe 59.208%, and Al 1.462%. This research shows a simple way to process iron oxide particles as a form of Konsern for the environment.
