Title:
DISPERSION SOLUTION OF SURFACE-COATED METAL PARTICULATE, AND METHODS OF PRODUCING SINTERED ELECTRICAL CONDUCTOR AND ELECTRICALLY CONDUCTIVE CONNECTION MEMBER, INCLUDING STEPS OF APPLYING AND SINTERING THE DISPERSION SOLUTION
Document Type and Number:
Japanese Patent JP2017002364
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide dispersion solution or the like of surface-coated metal particulates, the dispersion solution allowing for production of a metallic sintered compact excellent in electrical conductivity and tight adhesion.SOLUTION: The dispersion solution of surface-coated metal particulates (P) is characterized in that the surface-coated metal particulates are dispersed in an organic solvent (S) containing an organic compound (S1) having at least one hydroxyl group. The surface-coated metal particulate comprises: a metal nuclear particle (P1) having an average primary particle size of 5-300 nm and having the surface coated with a polymer dispersant (D); a first coated part (B1) formed on at least a part of the surface of the metal nuclear particle (P1) and containing mainly a metal oxide being an oxide of the same metal as that of the metal nuclear particle; and a second coated part (B2) formed on at least one side of the surface of the particle (P1) on which the coated part (B1) is not present and the surface of the coated part (B1), and containing mainly a metal compound formed by reaction of the metal ion being the ion of the same metal as that of the metal nuclear particle with carboxylic acid.SELECTED DRAWING: None
