銀微粒子の製造方法
Document Type and Number:
Japanese Patent JP5376109
Kind Code:
B2
Abstract:
Fine silver particles which contain a halogen in an amount of 5.0OE0-8 to 1.5OE0-3 mol per mol of the silver. Also provided is a process for producing the fine silver particles which includes a step in which a reducing agent is added to a silver ion solution to reduce the silver ions and thereby precipitate fine silver particles, the silver ion reduction being conducted in the presence of a nucleating substance which constitutes nuclei for the fine silver particles. Furthermore provided is an apparatus for producing the fine silver particles which comprises a silver ion solution tank, a first pipeline connected to the silver ion solution tank, an aqueous-ammonia-solution tank, a second pipeline connected to the aqueous-ammonia-solution tank, a reducing-liquid tank, a third pipeline connected to the reducing-liquid tank, and a fourth pipeline extending from a part where the first and second pipelines cross each other. The apparatus has a constitution in which a reducing liquid supplied through the third pipeline is mixed with a liquid mixture of a silver ion solution and an ammonia solution, the liquid mixture being supplied through the fourth pipeline.
