摘要：All kinds of spherical ultrafine nickel powders, varied in mean particle size (0.1-5μm),were prepared by chemical reduction in aqueous solution. The pH effect on the production of nickel powder and the main factors of their morphological control were studied. The nickel powder with purity 98.5% was obtained in the Na2CO3-NaHCO3 buffer system at pH 9.2-11. The surface-rubbed stirring oar helped to the preparation of nickel particles. The mean particle size was decreased to subndcron range by using AgNo3 as nucleating agent. PVP was an efficient agent to regulate particle shape andreduce aggregation.
