Electrochemical production of Al–Mn alloys during the electrodeposition of aluminium in a laboratory cell

Awayssa, Omar; Haarberg, Geir Martin; Meirbekova, Rauan; Saevarsdottir, Gudrun Arnbjorg (Elsevier BV, 2021-04)

This study reports the direct production of an aluminium–manganese alloy during aluminium electrolysis in fluoride-based melts. Experiments were conducted in a laboratory cell dedicated for current efficiency measurements. The temperature was varied ...
Influence of Phosphorus on Current Efficiency in Aluminum Electrolysis at Different Current Densities

Meirbekova, Rauan; Haarberg, Geir Martin; Thonstad, Jomar; Saevarsdottir, Gudrun Arnbjorg (The Electrochemical Society, 2017)

Many factors may contribute to loss of current efficiency (CE) in aluminum reduction and one of them is a presence of impurities. In this work, the effect of phosphorus on CE is studied in a laboratory cell at different current densities. Due to a ...
