Interaction of Gallium and Oxygen Ions in Molten Chlorides of Alkali Metals

  • Published:
Radiochemistry Aims and scope

Abstract

Interaction of gallium cations with oxygen anions in the NaCl-KCl molten equimolar mixture and NaCl-KCl-CsCl eutectic salt mixture as influenced by the activity of the oxygen ions in the melt was studied at 823–1023 K by potentiometric titration in an electrochemical cell with two platinum-oxygen electrodes and a solid electrolyte membrane. The form of occurrence of gallium in the molten salts and the proceeding chemical reactions were discussed. The solubility of gallium oxychloride was determined, and the thermodynamic characteristics of its formation were calculated.
