PROCESS FOR PRODUCING FLAKY SILVER POWDER AND FLAKY SILVER POWDER PRODUCED BY THE PROCESS

摘要

A process for producing a flaky silver powder which has excellent powder properties and which, when used to prepare a conductive paste, can prevent the paste from giving a conductor having increased resistance. The silver powder can prevent a conductivity decrease without fail. The process for producing a flaky silver powder is characterized by comprising: a dispersion step in which a fine silver powder composed of approximately spherical silver particles is dispersed in a solvent to prepare a slurry; a processing step in which the slurry and medium beads having a particle diameter of 0.2 mm or smaller are introduced into a bead mill and mixed and stirred to plastically deform each silver particle to form flaky silver particles; a separation/collection step in which the slurry is separated from the medium beads and the flaky silver particles are collected; and a washing/drying step in which the flaky silver particles collected are washed and dried to remove impurities and water and obtain the flaky silver particles.
