Abstract

Procédé de production de Ti ou d'un alliage de Ti à l'aide de la réduction par Ca, qui comporte une étape de réduction consistant à introduire du sel fondu contenant CaCl2 et dans lequel est dissous Ca dans une cuve de réaction (1) et à faire réagir Ca dans le sel fondu avec un chlorure métallique contenant TiCl4, pour produire des particules de Ti ou des particules d'alliage de Ti dans le sel fondu, et une étape de séparation (7) consistant à séparer les particules de Ti ou les particules d'alliage de Ti formées dans le sel fondu dudit sel fondu. Il est préférable d'ajouter une étape d'électrolyse (8) destinée à électrolyser le CaCl2 extrait de la cuve de réaction (1) en Ca et en Cl2, le Ca formé étant utilisé pour la réaction dans la cuve de réaction (1) en vue de la formation de Ti ou d'un alliage de Ti. Dans l'étape d'électrolyse (8), l'utilisation d'une électrode en alliage comportant de l'alliage de Ca fondu en tant que cathode améliore l'efficacité du courant électrique et l'alliage de Ca fondu peut également être utilisé efficacement en tant que milieu de transport de Ca afin d'augmenter la concentration en Ca. Ledit procédé permet la production d'un Ti métallique de grande pureté, avec un bon rendement et à faible coût.
