Conductive paste for the silver powder and a conductive paste

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a silver powder capable of manufacturing, without using, as reductants, polyhydric phenols such as hydroquinone, etc., a silver powder having an average particle diameter D₅₀ of 0.1 μm or above and below 1 μm and a maximal particle diameter D_max of 4 μm or below; and the silver powder.;SOLUTION: In a method for manufacturing a silver powder wherein silver particles are reduced and deposited by adding a reductant to an aqueous reaction system including silver ions, at least one type selected from the group consisting of fatty acids, fatty acid salts, and fatty acid esters is added to the aqueous reaction system prior to the addition thereto of the reductant, and a chelating agent is added to the aqueous reaction system following the addition thereto of the reductant.;COPYRIGHT: (C)2014,JPO&INPIT
