A review of Structure, Properties, and Chemical Synthesis of Magnetite Nanoparticles

Extensive studies were devoted to iron oxide nanoparticles (IONPs), in recent years. Iron oxides are chemical compounds that have various polymorphic forms, including maghemite (γ-Fe2O3), magnetite (Fe3O4), and Hematite (α-Fe2O3). Among them, the most important studied is (Fe3O4) due its low cost toxicity, besides unique magnetic physicochemical characteristics which qualified it for use applications such as biomedical technological applications. Magnetic particles should be small a narrow size distribution these The smaller of particles, greater their reactivity biodegradability. In this review, we display summary information terms structure, characteristics, preparation methods. Because prepared strategy has been proven critical preferable control particle shape, addition, producing monodispersed with direct effect on applications, special attention will placed techniques Hydrothermal synthesis, Co-precipitation technique, Sol-Gel process, thermal decomposition method. This review offers specific selecting appropriate synthetic methods obtaining sizes, shapes, properties (NPs) target
