Patent ID: 8916068

Claim:
A method for producing a silver micropowder comprising a step of reducing a silver compound with a reducing agent of an alcohol or polyol under presence of an amine A having an unsaturated bond and having a molecular weight of from 200 to 400 to obtain coated silver particles with the primary amine A having a mean particle diameter D TEM of from 3 to 20 nm or an X-ray crystal particle diameter D X of from 1 to 20 nm, a step of mixing the silver particles coated with the primary amine A with a liquid organic medium to be silver particles monodispersed in the liquid organic medium, a step of mixing the silver particle dispersion and hexylamine, a step of keeping the mixture liquid at 5 to 80° C. with stirring to thereby form precipitated particles, and a step of collecting the precipitated particles as a solid fraction through solid-liquid separation.
