Mass- and Heat Transfer during Dissolution of Alumina
Laboratory Evaluations of Ceramic Sidelining Materials.
Silicon-nitride bonded SiC sidelining materials are today the state of the art in modern prebake aluminium cells. SINTEF started in early1990's procedures for performing relevant test methods and quality evaluations of the different commercial materials available on the market. The test methods deve...

Current Efficiency in Hall-Héroult Cells: The Role of Mass Transfer at the Cathode
The current efficiency (CE) in aluminium cells is governed by transport of dissolved metal (mainly sodium) across the boundary layer at the cathode. The transport takes place by ordinary mass transfer, but since solutions of alkali metals and their salts show electronic conductivity, the CE is also ...

The Future of the Hall-Héroult Technology
In the authors' opinion, it is not likely that there will soon be an alternative to the Hall-Héroult process for making primary aluminium. The energy consumption in the traditional process is steadily decreasing, and there is still more room for improvement. The present paper discusses some opportun...
