Abstract

See full text

Disclosed herein are methods for producing an aluminum-scandium alloy comprising 0.41-4 wt % of scandium which can be used in industrial production setting. The method is carried out by melting aluminum and a mixture of salts comprising sodium, potassium and aluminum fluorides followed by performing simultaneously, while continuously supplying scandium oxide, an aluminothermic reduction of scandium from its oxide and an electrolytic decomposition of the formed alumina. Periodically, at least a portion of the produced alloy is removed, aluminum is then charged, and the process of alloy production is continued while supplying scandium oxide. Also disclosed is a reactor for producing an aluminum-scandium alloy pursuant to the methods described herein.
