| Abstract: | Through improving the experimental technique and regulating the ratio of precursor,Fe3O4 nanoparticles were preparaed by hydro-thermal method and the widespread problem of oxidation in the process of Fe3O4 particle preparation was effectively overcome.The sample phase structure and particle sizes were determined by X-ray diffraction(XRD),scanning electron microscopy(SEM),and transmission electron microscopy(TEM).It was confirmed the magnetic particles obtained were pure Fe3O4 nanoparticles.Through analyses ... |
