SILVER MICROPARTICLE-CONTAINING COMPOSITION, PROCESS FOR PRODUCTION OF THE COMPOSITION, PROCESS FOR PRODUCTION OF THE SILVER MICROPARTICLE, AND PASTE CONTAINING THE SILVER MICROPARTICLE

摘要

A composition containing fine silver particles which have a uniform particle size, can form a fine drawing pattern, and have a small environmental impact, a method for producing that composition, a method for producing fine silver particles, and a paste having fine silver particles are provided. The fine silver particles are produced by carrying out a fluid preparation step of preparing a reduction fluid, a silver reaction step, and a filtration/washing step. The reaction step is carried out by adding an aqueous silver nitrate fluid to a reduction fluid whose temperature has been increased to a range between 40 and 80°C. The aqueous silver nitrate fluid is added at a stretch. The composition containing fine silver particles is produced by dispersing the composition containing the fine silver particles in a polar fluid.
