Abstract

The properties of potential electrolytes for the recovery of Ti, Zr and Hf by a fused salt electrolytic process employing solutions of TiCl4, ZrCl4 and HfCl4 in alkali and alkaline earth chloride melts are discussed in terms of thermal stability. Pressuretemperature relationships for these systems are analyzed, and methods for calculating activities of complex ionic species in solution are presented.RésuméEn termes de stabilité thermique, les auteurs discutent des propriétés d'électrolytes applicables à l'obtention électrolytique du Ti, du Zr et du Hf en solutions de TiCl4, de ZrCl4, de HfCl4 dans des chlorures fondus de métaux alcalins et alcalins-terreux. Pour ces systémes, les relations pression-température sont examinées, et des méthodes de calcul d'activité d'espéces complexes ioniques en solution sont suggérées.
