Abstract
Provided is a method of producing an Al—Sc based alloy suitable for production of an Al—Sc based alloy that: eliminates the needs for equipment for heating in an inert gas atmosphere or a vacuum atmosphere, a reducing agent such as metal Ca, and equipment and power for molten salt electrolysis; can be performed adequately by heating up to 1,050° C.; and enables continuous operation. The method of producing an Al—Sc based alloy includes: loading into a reaction vessel metal aluminum (Al), a metal fluoride salt, and a scandium compound; elevating a temperature of a reaction system to from 700 to 1,050° C. to form a molten metal layer including molten metal aluminum serving as a lower layer and a molten salt layer in which the metal fluoride salt and the scandium compound are melted serving as an upper layer; and transferring a scandium ion (Sc) generated in the molten salt layer side to the molten metal layer side. The metal fluoride salt has a melting temperature lower than the reaction temperature and has a density in a range of from 70 to 95% of the density of the molten metal aluminum, at the reaction temperature.
