This paper presents the method for preparation the fine Ag powder with a particles size smaller than 2 μm. Reduction was performed from the nitrate solution directly by the vigorous stirring at the room temperature by the use of ascorbic acid as the reducing agent and polyvinylpyridine as the protecting agent. Silver powder with nearly spherical particles and size of micrometers were prepared by the chemical reduction and characterized by the scanning electron microscope (SEM). The SEM analysis has shown that preferred size, less than 2 μm was obtained. Silver with purity of 99.9% or more was obtained.
