COMPOSITE COPPER POWDER AND CONDUCTIVE COMPOSITION INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a powder comprising copper as a base material that can increase the conductivity of a conductor formed from a conductive composition.SOLUTION: The composite copper powder has a composite copper particle including a base material copper particle and a silver-containing complex compound present on the surface of the base material copper particle. The base material copper particle has a core material particle of copper and a silver-coated copper particle having a coating layer of silver present on the surface of the core material particle. The silver-containing complex compound has a complex compound of a carboxylate of silver and an amine compound and preferably, the silver-containing complex compound comprises a complex compound of a 1-5C carboxylate of silver and a saturated or unsaturated aliphatic amine.SELECTED DRAWING: None
