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.
