Abstract:
Fe3O4 nanoparticles were analyzed by co-precipitation method, where the effects of the process factors such as initial pH, temperature, time of treatment on the crystal purity and size of the prepared particles were investigated. At the same time, the influence of organic compound covering products and the system of ethanol- water were studied. The structure and particle size of the nanoparticles were characterized by X-ray powder diffraction （XRD） and transmission electron microscope （TEM）. It was shown that the products were perfect grown crystal nanoparticles Fe3O4 with the average particle size of about 14 nm.[著者文摘]
Key words:
