Synthesis and Characterization of Fe3O4 Magnetite Nanoparticles Coated with Silica Nanoparticles

Abstract Fe₃O₄ nanoparticles have been successfully synthesized by modification of the preparation method of Fe₃O₄ nano-particles, which were prepared from Iron (III) Chloride hexahydrate FeCl₃.6H₂O, Ferrous Chloride FeCl₂.4H₂O, Ammonia Solution (NH₄OH)and silica nanoparticles. In this study, a new preparation of Fe₃O₄ nanoparticles and Fe₃O₄ nanoparticles coated with silica nanoparticles were reported. The characterization of Fe₃O₄ nanoparticle and Fe₃O₄ nanoparticles coated with Silica nanoparticles is done by TEM, XRD and Spectrophotometer.
