COBALT PLATED COPPER FINE POWER, CONDUCTIVE PASTE PRODUCED BY USING THE SAME, AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a material smaller in specific resistance as an electrode material of a laminated ceramic capacitor, in particular, copper fine powder having a higher TMA value for allowing to set the particle size of conductor particles in a sintering paste for configuring an inner electrode to the order of 0.1-1 μmφ in order to prevent a short circuit among laminated electrodes and allowing to alternately stack the electrodes and dielectrics of the laminated ceramic capacitor in order to simultaneously sinter them at a high temperature.;SOLUTION: Cobalt coated copper fine power has a cobalt layer on a surface of the copper fine powder formed by disproportionation reaction. In a method of producing the cobalt coated copper fine powder, the copper fine powder is formed by disproportionation reaction of cuprous oxide, the copper fine powder is plated with palladium (Pd) by electroless displacement plating, and cobalt is coated on it by electroless plating.;COPYRIGHT: (C)2013,JPO&INPIT
