METHOD FOR PRODUCTION OF ALUMINUM-SCANDIUM ALLOY Russian patent published in 2022 - IPC C25C3/06 C22C21/00 C25C3/36 

FIELD: metallurgy.

SUBSTANCE: invention relates to methods for the production of an aluminum-scandium (hereinafter – Al-Sc) alloy. The method for the production of Al-Sc alloy, providing for combination of metal-thermal and electrolytic reactions, includes provision of electrolyzer containing ScF₃ and AlF₃ and a portion of at least one of LiF, NaF, or KF, bringing a cathode containing aluminum into contact with electrolyzer, bringing an anode into contact with electrolyzer, wherein, for a metal-thermal reaction, a portion of Sc₂O₃ is added to electrolyzer, while aluminum ion and scandium ion react with the cathode to obtain Al-Sc alloy, and, for an electrolytic reaction, electric current is applied to the cathode, while aluminum ion and scandium ion react with the cathode to obtain Al-Sc alloy, after provision of the reaction of scandium ion with the cathode, electrolyzer contains ScF₃, AlF₃, and at least one of LiF, NaF, or KF, and the cathode contains the alloy.

EFFECT: invention is aimed at improvement of a method for the production of Al-Sc alloy.
