Penentuan Sifat Magnetik Dan Struktur Partikel Oksida Besi Pasir Pantai Sunur…

Iron oxide nanoparticle is particle with a diameter between 1-100 nanometers. The iron oxide of natural sand consists of magnetite (Fe3O4), hematite (α-Fe2O3), or maghemite (γ-Fe2O3). The aims of this study is to prepare magnetic nanoparticles from Sunur Beach sand Pariaman district West Sumatera using a two-stage ball milling technique and determine their magnetic and structural properties. …
