Title:
SILVER PARTICLES CONTAINING COPPER, METHOD FOR PRODUCING THE SAME, AND DISPERSION USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/073420
Kind Code:
A1
Abstract:
Provided is a method suitable for the simple, mass production of nanoparticles having a uniform grain size, and silver particles produced by the same production method.
One or more selected from the group consisting of copper, copper compounds, and copper ions is added prior to completion of the reduction reaction during the silver particle reaction in which a silver compound solution, protector, and reducing agent solution are mixed and reduction is performed. As a result, regardless of the reaction scale, it is possible to produce particles having a uniform grain size by a reaction in which silver particles are obtained such that the average grain size in the solution is 1 to 100 nm.
