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

摘要

The present invention relates to a method for producing core-shell type metal fine particles formed by a shell component containing copper and a core component containing copper, comprising the steps of: preparing copper particles and silver particles; A step of adsorbing a plurality of the silver particles on the surface of the copper particles through simultaneous decomposition in an organic solvent and a step of heating the copper particles on which the silver particles have been adsorbed, And fusing the silver particles with each other to form a shell component containing silver on the surface of the copper particles.
