The nickel powders were synthesized by the reduction of liquid phase in ethylene glycol and characterized by Specific Surface, XRD and SEM. Thermodynamics of preparation of ultrafine and nanometer nickel powder from ethylene glycol(EG) and Ni(OH)2 was studied and plotted the E-pH diagram of Ni-EG-H2O. The oxidation product of ethylene glycol was analyzed from E-pH graph and verified by XRD. The size of nickel powders was about 0.15μm by SEM and 0.088μm by BET. The oxidation product of ethylene glycol was CO32-.
