MT8104 - Electrolysis of Light Metals


Lessons are not given in the academic year 2023/2024

Course content

The course is offered every alternate year, next time will be autumn 2024. The course includes fundamental theory for industrial electrowinning in molten salts, with special emphasis on aluminium. Topics: - Phase diagrams. - Electrolyte structure, thermodynamics. - Physicochemical properties. - Electrode reactions. - Current efficiency. - Metal solubility. - Inert electrodes.

Learning outcome

The candiate should have a fundamental theoretical understanding of the principles for the production of aluminium molten salts electrolysis.
