Direct electroreduction of indium and tin oxides in molten salts
Qin, Bo; Cui, Peng; Martinez, Ana Maria; Aune, Elizabeth Ragnhild; Haarberg, Geir Martin ( Electrochemical Society Inc. , 2014 , Article)Indium is a rare metal. The largest end use for indium is in thinfilm coatings as indium oxide combined with 10 percent tin oxide (ITO). However, indium has recycling rates less than 1%. Indium and tin are especially well ... -

Electrodeposition of liquid metals from molten salts
Haarberg, Geir Martin ( Electrochemical Society Inc. , 2014 , Conference Paper)Many important metals are being produced by electrolysis in molten salts (aluminium, sodium, rare earths and other reactive metals). Also industrial electrorefining of aluminium takes place in a molten salt electrolyte. ... -
Electrodeposition of Mg-Ni-Al Alloy in low temperature molten salts
Xu, Junli; Zhang, Xia; Shi, Zhongning; Haarberg, Geir Martin ( Electrochemical Society Inc. , 2014 , Conference Paper)Mg-Ni-Al alloys were prepared in urea-acetamide-NaBr low temperature molten salts by electrodeposition method. Effects of electrodeposition parameters such as deposition temperature and time on the composition and ... -
The Role of Key Impurity Elements on the Performance of Aluminium Electrolysis - Current Efficiency and Metal Quality
Al-Mejali, Jassim Ali (2015 , Master Thesis)Impurities such as phosphorus and silicon mainly enter the aluminium electrolysis process with alumina. These impurities dissolve in the electrolyte and affect the performance of the electrolysis, the emissions from the ... -
The Performance of Aluminium Electrolysis in A Low Temperature Electrolyte System
Cui, Peng; Solheim, Asbjørn; Haarberg, Geir Martin ( wiley , 2016 , Book chapter)The electrolyte based on the molten KF‐AlF3‐NaF system was investigated for low‐temperature aluminium electrolysis in laboratory scale. The current efficiency for aluminium deposition was determined from the amount of ... -
The Performance of Aluminium Electrolysis in Cryolite Based Electrolytes Containing LiF, KF and MgF2
Cui, Peng; Solheim, Asbjern; Haarberg, Geir Martin ( John Wiley & Sons, Inc. , 2015 , Book chapter) -
The Role of Key Impurity Elements on the Performance of Aluminium Electrolysis -Current Efficiency and Metal Quality
Al-Mejali, Jassim Ali; Haarberg, Geir Martin; Bensalah, Nasr; Benkahla, Ben-Aissa; Lange, Hans Petter ( wiley , 2016 , Book chapter)The behaviour of phosphorus and silicon in industrial aluminium cells was measured in QATALUM cells by analysis of bath and metal after addition of AlPO4, Na3PO4 and SiO2 to the bath. Phosphorus showed a much longer retention ...
