Preparasi Nanopartikel Oksida Besi Berbasis Pasir Alam Logas Didoping Alumini…

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 nanoparti…
