Abstract: Nitrided-iron nanometer powder is prepared by thermal chemical vapor-phase reaction method,using FeCl2·nH2O and NH3 as starting material.The physical properties of the powder is measured by means of XRD,XPS,TEM,VSM etc,and physical phase shape, size and magneticpropertiesof the powderis also characterized.Experimentresults show nitridediron ultrafine powder of uniform,high pure,chain-of-spherical and high magnetics can be prepared by improving synthesis reaction instrument.The physical property index of the powder prepared in this instrumentis preferable to Tanaka′s same study results. |
