N2 - The Hydrazine hydrate (N2H4·H2O) as the reducing agent, AgNO3 as the source of Ag, the silver nanopowders with good dispersity were prepared by liquid phase reduction method. The morphology, composition and structure of the particles were investigated by transmission electron microscopy (TEM), X-ray fluorescence (XRF), and X-Ray diffraction (XRD), respectively. Single factor experiments were taken by studying the pH value and the selection of dispersers. Using the orthogonal design method, the optimal conditions to prepare the silver nanopowders were obtained by studying the effects of following factors, such as the concentration of AgNO3, the doses of disperser and the temperature on the dispersion of the silver powder. The results show that under optimization conditions, the pure silver nanopowders with near-spherical shapes are synthesized using the AgNO3(0.5mol·L-1), N2H4·H2O (0.5mol·L-1), PVP as disperser, PVP/AgNO3 mass ratio of 9:100, pH=8 at 30°C.
