Abstract

See full text

The present invention provides a method for producing silver particles, the method capable of adjusting the particle diameter to be within the range of several tens of nanometers to several hundreds of nanometers and also producing silver particles with a uniform particle diameter. The present invention relates to a method for producing silver particles by heating of a reaction system containing a thermally-decomposable silver-amine complex precursor, including a process of producing a silver-amine complex, a process of adding an organic compound having an amide (carboxylic amide) as a skeleton to a reaction system, and a process of heating the reaction system, in which a water content in the reaction system before the heating is 20 to 100 parts by weight relative to 100 parts by weight of the silver compound. The present invention can produce uniform silver particles while the particle diameter is controlled.
