Abstract
Laboratory tests for cathode wear identify some variables as important, and eliminate others. These results are compared with models and with industrial potline experience. The research team Electrolysis in SINTEF Materials and Chemistry offers a high level of competence in the field of light metals production, molten salt chemistry, and particularly, the process of aluminium electrolysis. The activities cover fundamental as well as applied research in close collaboration with the industry and NTNU (Norwegian University of Science and Technology). This paper reviews the recent activities in the Durable Materials in Primary Aluminium Production (DuraMat) project on cathode wear, a phenomenon that is of great interest for all primary aluminium producers.
