Abstract
Ag powder was prepared from <TEX>$AgNO_3$</TEX> by wet chemical reduction method using various reduction agent system involving <TEX>$AgNO_3$</TEX>, <TEX>$AgNO_2$</TEX>(AgCl) and Ag complex ion aqueous solution. The pure Ag powder could be prepared regardless of reaction system but the particle shape and distribution were affected very much according to the kind of reduction agents and reaction systems. The optimum reaction system for the preparation of the silver powder having the uniform particle shape and size distribution was Ag complex ion aqueous solution-reduction agent system and in particular, <TEX>$H_2O_2$</TEX> and <TEX>$C_6H_8O_6$</TEX>as a reduction agent leaded the more uniform particle shape and size distribution.
