Thermal Conductivity of Compounds Present in the Side Ledge in Aluminium Electrolysis Cells
This paper presents a database for the temperature-dependent thermal conductivity of compounds potentially present in the side ledge formed in aluminium electrolysis cells, between the molten electrolyte used to dissolve the alumina and the side wall. The database is given in the form of an analytical model with sets of parameters for each compound. To determine the model parameters, we considered a robust optimisation approach based on reliable models derived from fundamental physics. Where data are missing, first-principles calculations are utilized to estimate the parameters directly. For all compounds for which data are available, the model’s predictions are found to be in very good agreement with reported experimental data.
