SILVER-COATED COPPER POWDER

摘要

PROBLEM TO BE SOLVED: To provide silver-coated copper powder capable of exhibiting more excellent conductivity.SOLUTION: In the silver-coated copper powder composed of dendrite-like silver-coated copper powder particles where the surface of copper powder particles is coated with silver, the ratio (BET specific surface area/sphere approximation specific surface area) of the specific surface area (referred to "BET specific surface area") measured by a BET one point method to the specific surface area (referred to "sphere approximation specific surface area") measured by a laser diffraction scattering particle size distribution measuring apparatus is 6.0-15.0.
