METHOD FOR PRODUCING CORE-SHELL TYPE METAL FINE PARTICLES, CORE-SHELL TYPE METAL FINE PARTICLES AND METHOD FOR PRODUCING CONDUCTIVE INK AND SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide core-shell type metal fine particles having excellent conductivity.SOLUTION: There is provided a method for producing core-shell type metal fine particles formed from a copper-containing core component and a silver-containing shell component, which comprises: a step of preparing copper particles and silver particles; a step of simultaneously dispersing the copper particles and silver particles in an organic solvent to adsorb a plurality of the silver particles on the surface of the copper particles; and a step of heating the copper particles on which the silver particles are adsorbed to fuse the plurality of the silver particles to one another, which are adsorbed on the surface of the copper particles and form the silver-containing shell component on the surface of the copper particles.
