Abstract

L'invention concerne un procédé permettant de réduire un oxyde métallique, tel que du titane à l'état solide, dans une cellule électrolytique. Ladite cellule électrolytique comprend une anode, une cathode et un électrolyte fondu. L'électrolyte comprend des cations métalliques capables de réduire chimiquement l'oxyde métallique. Ledit oxyde métallique à l'état solide est immergé dans l'électrolyte. Ledit procédé consiste à faire fonctionner la cellule à un potentiel au-dessus du potentiel auquel les cations métalliques capables de réduire chimiquement le dépôt d'oxyde peuvent se déposer sous forme de métal sur la cathode. De ce fait, le métal réduit chimiquement l'oxyde métallique.
