Formation of Transition Metal Sulfide Particles by Anode Discharge Electrolysis of Molten LiCl-KCl-KSCN System

Abstract

Anode discharge electrolysis has been conducted with a molybdenum anode and a LiCl-KCl-KSCN system under 1 atm of Ar at 723 K. A discharge was generated between the melt and the anode whose tip was positioned above the bath surface. After anode discharge electrolysis, black powder was obtained from the melt. From the results of XRD, SEM, EPMA and XPS, the powder obtained was identified to be MoS₂ nano particles. In the same manner, when anode discharge electrolysis was conducted with a tungsten anode, WS₂ particles were obtained.
