Abstract： To prepare nickel nano-particles, the reduction process of liquid phase with NiSO4 as main salt，N2H4·H2O as reductant, NaH2PO2·H2O as inducer was used. The micro-morphology, component and functional structure of the nickel nano-particles were characterized with scanning electron microscope（SEM）, energy dispersive spectrometry （EDS） and X ray diffraction (XRD). The effects of raw molar ratio n(NiSO4):n(N2H4· H2O), inducer on the micro-morphologies and lattice parameters of the nickel nano-particles were studied. The results show that particle sizes of the powders increase with increasing raw molar ratio n (NiSO4):n (N2H4·H2O). When the raw molar ratio excesses 1:2, the reaction is controlled by simultaneously depositing process of Ni -P nano-particles, which can inhabits the nucleation of nickel particles. The lattice distortion aggravates to form amorphous nickel nano-particles with increasing inducer contention to 0.4 mol/L.
