Abstract
PRECIS DE LA DIVULGATION:
Procédé de séparation des tétrachlorures de zirco-nium et de hafnium à partir de leurs mélanges qui consiste à
procéder à une absorption sélective des vapeurs de ZrCl4 et de HfCl4 par un solvant fondu circulant à contre-courant desdites vapeurs dans une colonne à distiller, ledit solvant étant cons-titué par un chloroaluminate et/ou un chloroferrate de potassium.
Le procédé permet d'obtenir du HfCl4 à basse teneur en zirco-nium et du ZrCl4 exempt de hafnium, à partir duquel on peut pré-parer du zirconium de pureté nucléaire.
