METHOD FOR ELECTROLYTIC PRODUCTION OF ALUMINUM ALLOYS WITH SCANDIUM Russian patent published in 2024 - IPC C25C3/06

Abstract RU 2819113 C1

FIELD: metallurgy of non-ferrous metals.

SUBSTANCE: invention relates to production of functional aluminum alloys. Method for electrolytic production of aluminum alloys with scandium, including electrolysis of melt KF-NaF-AlF₃-Al₂O₃ with additives of Sc₂O₃ and Al₂O₃ in electrolysis cell with vertically arranged anode and cathode, electrolysis is carried out at temperature from 750 to 820 °C, anode current density from 0.6 to 1.0 A/cm², note here that graphite cathode with boride coating and low-consumption anode of pre-oxidised metal alloy based on Fe-Ni-Cu system are used.

EFFECT: obtaining aluminum alloys with scandium while avoiding emission of greenhouse gases.
