Investigation of phase transformation related electrical conductivity of long-term heat treated aluminium electrolysis cathodes

Abstract

Article Highlights Measuring the electrical properties of the materials used on the cathode side of an aluminium electrolysis cell in their initial state and after a service time of 5 years. Connecting the changes in electrical conductivity to the chemical compositions, supported by numerical calculations. Contributing to a better understanding how to increase the energy efficiency of primary aluminium production.
