METHOD FOR MANUFACTURING SILVER PARTICLES

摘要

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.

1. A method for producing silver particles by use of a thermally-decomposable silver-amine complex as a precursor and heating of a reaction system containing the precursor, comprising:
a process (a): mixing a thermally-decomposable silver compound with an amine to produce a silver-amine complex as a precursor; a process (b): adding an organic compound, which has an amide as a skeleton, represented by a following formula to a reaction system (R is hydrogen, hydrocarbon, an amino group, or a combination thereof; R′ and R″ are hydrogen or hydrocarbon); and a process (c): heating the reaction system, wherein a water content in the reaction system before the heating in the process (c) is 20 to 100 parts by weight relative to 100 parts by weight of the silver compound.
