AbstractAbstract PDF
Ag powder was prepared from AgNO_3 by wet chemical reduction method using various reduction agent system involving AgNO_3, AgNO_2(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, H_2O_2 and C_6H_8O_6as a reduction agent leaded the more uniform particle shape and size distribution.
