Потенциометрическое исследование вольфрамсодержащих хлоридных расплавов

Abstract

Electrode potentials of tungsten were measured in NaCl–2CsCl and 3LiCl–2KCl based melts at 450–850 oC under the atmosphere of high purity argon. Tungsten ions were introduced into the melt by anodic dissolution of the metal. Tungsten anodic dissolution is a four-electron process and W(IV) ions are present in the melt in equilibrium with the metal. Forma lstandard W/W(IV) electrodepotentials were determined.
