Title:
SILVER MICROPARTICLE POWDER, METHOD FOR PRODUCING SAID POWDER, SILVER PASTE USING SAID POWDER, AND METHOD FOR USING SAID PASTE
Document Type and Number:
WIPO Patent Application WO/2010/073705
Kind Code:
A1
Abstract:
Provided is a method which is suitable for the mass production of nanoparticles of uniform grain size. Also provided are a nanoparticle powder obtained by this method, a dispersion containing these nanoparticles, and a paste containing these nanoparticles. The method for producing silver particles comprises a step for obtaining particles having an average grain diameter (DTEM) of between 5 and 100 nm as measured using a transmission-type electron microscope, in which silver is reduced in a silver solution containing a protectant comprising an organic substance and a copper component in an amount of 1 to 1,000 ppm with respect to the amount of silver.
