Paper Title:
Electrochemical Behavior of Magnesium and Aluminium Ions in Alkali Chloride Melt
  Abstract

The electrodeposition of aluminium and magnesium in lithium chloride-sodium chloride (mass 5:1) melt at 700°C has been studied using cyclic voltammetry, square wave voltammetry and chronopotentiometry. The reduction of aluminium and magnesium ions on tungsten electrode are both reversible processes, with three and two electrons exchanged: Al3++3e → Al, Mg2++2e →Mg. The diffusion coefficients of Al3+ and Mg2+ were determined as 2.72×10-5 cm2 s-1 and 1.58×10-4cm2 s-1 respectively. A laboratory test of the direct production for the Mg-Al alloy was performed to show the feasibility of electrochemical co-deposition of magnesium base alloys.
