Synthesis of nano-sized magnetic iron oxide by a simple and facile o-precipitation method

Magnetic iron oxide (Fe3O4) in nano form has been synthesized by a simple wet chemical method involving co-precipitation using salt and ammonium hydroxide as precipitating agents. Characterization of the nanoparticles were carried out XRD, FTIR, FESEM VSM techniques. Crystallite sizes determined from XRD data found to be between 6.8 12.6 nm with face center cubic crystal structures. The lattice parameter was 8.34 Å. microstructure revealed spherical like average particle size of. saturation magnetization magnetite measured 49.88 emu/gm. Fe3O4 is considered potentiality good magnetic material diverse applications.
