Methods and apparatus for manufacturing silver powder

Abstract

The purpose of this invention is to provide a method for manufacturing silver powder, wherein a silver-containing solution flows in a flow path, a pH adjuster is added to the flow path at a pH adjuster addition position in the middle of the flow path, a chelating agent is added to the flow path at a chelating agent addition position further downstream of the pH adjuster addition position, and a hydrazine-based reducing agent is added to the flow path at a reducing agent addition position further downstream of the chelating agent addition position, thereby reducing and precipitating silver powder within the flow path.
