Discharge electrolysis in molten chloride: formation of fine silver particles

Abstract

A relatively stationary discharge was generated in molten chloride utilizing a simple apparatus and successfully achieved at electrolysis. Fine silver particles were obtained using a LiCl-KCl-AgCl eutectic melt in an argon atmosphere. SEM observations of the silver particles showed them to be almost spherical and the size to be strongly dependent on the experimental conditions. This new kind of discharge electrolysis is expected to be adopted as a new method for metal powder production.
