Abstract

Le procédé de production d'un alliage d'aluminium-strontium de l'invention consiste en la décomposition électrolytique d'un bain de fusion composé d'un mélange de chlorure de strontium et de chlorure de potassium au niveau de l'anode et de la cathode. La cathode utilisée est un aluminium liquide agité pendant le procédé de décomposition électrolytique du bain de fusion aux chlorures. L'unité d'électrolyse de l'invention comprend un bain (1) présentant une anode (4) ainsi qu'une cathode (6). La cathode (6) est l'aluminium liquide se trouvant dans la partie inférieure du bain (1), lequel est doté d'un agitateur (8) et d'un élément (12) destiné à conduire du courant à la cathode (6), lequel présente un revêtement protecteur destiné à empêcher toute réaction chimique avec l'alliage.
