Magnetite Iron Oxide Nanopowder
This nanopowder are valuable technical materials. They are used for drug administration, hyperthermia and magnetic resonance imaging. In recent years, biologists have paid increasing attention to magnetic nanoparticles, including maghemite and magnetite, using them in agrotechnology because the compounds are a source of iron for living organisms and improve the metabolism of plants making them persistent under various stresses (drought, frost and phytopathogens). Chemical precipitation from aqueous solutions of iron salts is the most common method for synthesizing iron oxide nanopowders. There are many variations of this synthesis method. The boundary between the preparation of this nanopowder in one or another crystalline modification (γ-Fe2O3 or Fe3O4) is very thin. Since magnetite can be oxidized to maghemite during synthesis, but tends to be incompletely oxidized even with prolonged heating, the detailed study of the Magnetite iron oxide nanopowder requires methods that can differentiate between Fe3O4 and γ-Fe2O3, including the X-ray powder diffraction, with mandatory requirements. Calculation of unit cell parameters. The aim of this work is to synthesize iron oxide magnetite nanopowders by coprecipitation from aqueous solutions of iron (II, III) chlorides using three different procedures and to compare their structure and phase composition.
