Pre-heating of alumina. Weight of rafts at different temperatures
It has been suggested that the alumina added to aluminium electrolysis cells should be pre-heated to obtain more rapid dissolution and thereby smoother operation. To investigate the effect of pre-heating, the formation of alumina "rafts" upon feeding a batch of alumina to the surface of mo...

Wetting Phenomena in Aluminium Electrolysis
Interfacial tension and wetting phenomena are important in all industrial processes, and the aluminium electrolysis is no exception. The present paper explains some of the basic principles related to interfaces, including the Young equation and principles for computing the shape of surfaces. An anal...

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 ...
