Synthesis of Mono-Dispersed Fine Spherical Silver Powders by Chemical Reduction Method


Article Preview

The synthesis of spherical silver powders by chemical reduction method was investigated. Conductive metal pastes to have good properties in adhesion, stability, and conductivity, it is very important to control the purity, size, and shape of metal particles. In the present study, proper methods to control the properties of micron sized metal powders for conductive pastes are investigated. Chemical reduction method in aqueous solution was adapted to produce silver powder. The effects of reaction time, concentration of reductant and additives, and stirring speed were investigated, in experimental. Fine spherical silver powder of 0.5 to 3 ㎛ were synthesized from silver nitrate solution with hydroquinone as a reducing additive by liquid phase method, and some variables and reaction mechanism in conjunction with the particle morphology and size were studied.
