ELECTROCHEMICAL PROPERTIES OF MOLTEN LITHIUM-POTASSIUM CHLORIDE EUTECTIC MIXTURE HELD IN CONTACT WITH METALLIC NEODYMIUM AND DYSPROSIUM

Abstract

The corresponding rare earth metal (REM) ion concentration dependence of the reaction capacity (R) of molten lithium–potassium chloride eutectic mixture held in contact with neodymium and dysprosium has been investigated at 773, 873, and 973 K. The obtained data of R values permitted to determine the charge of Nd and Dy ions that go into the melt in the process of corrosion of REM studied and define concretely the mechanism of current-free transfer of REM onto more electropositive metals (for example, nickel).
