Abstract
The present invention provides silver nano-particles with excellent stability and conductivity by low-temperature calcining, a producing method for same, and a silver coating composition. A method for producing silver nano-particles comprising: preparing an amine mixture liquid comprising: an aliphatic hydrocarbon monoamine (A) with an aliphatic hydrocarbon group and one amino group, the aliphatic hydrocarbon group having 6 or more carbon atoms in total; an aliphatic hydrocarbon monoamine (B) with an aliphatic hydrocarbon group and one amino group, the aliphatic hydrocarbon group having 5 or less carbon atoms in total; and an aliphatic hydrocarbon diamine (C) with an aliphatic hydrocarbon group and two amino groups, the aliphatic hydrocarbon group having 8 or less carbon atoms in total; mixing a silver compound and the amine mixture liquid to form a complex compound; and thermally decomposing the complex compound by heating to form silver nano-particles.
