Title:
METHOD FOR PRODUCING SILVER PARTICLES, SILVER PARTICLES AND SILVER PASTE
Document Type and Number:
WIPO Patent Application WO/2017/018359
Kind Code:
A1
Abstract:
A mixed solution, in which at least a silver compound, a reducing agent and a dispersant are mixed, is obtained first (S1). After that, sheet-like or plate-like first silver particles and second silver particles which have a spherical shape or a shape closer to a sphere than the first silver particles, and which have a particle diameter that is smaller than the maximum side length of the first silver particles are produced by heating the mixed solution, thereby having the silver compound and the reducing agent react with each other (S2).
