• The Behavior of Additives LiF, MgF2 and KF on Current Efficiency in Aluminium Electrolysis 

      Cui, Peng; Qin, Bo; Haarberg, Geir Martin (Journal article; Peer reviewed, 2019)
      The effects of LiF, MgF2 and KF additions to the electrolyte on current efficiency were investigated during aluminium electrolysis using base NaF−AlF3−Al2O3 system with a cryolite ratio of 2.5, 4% Al2O3 and 5% CaF2 at 980°C ...
    • The durability of the thermally decomposed IrO2-Ta2O5 coated titanium anode in a sulfate solution 

      Xu, Wenting; Haarberg, Geir Martin; Seland, Frode; Sunde, Svein; Ratvik, Arne Petter; Holmin, Susanne; Afvander, Åsa; Gustavsson, John; Zimmerman, Erik; Årke, Torjus (Journal article; Peer reviewed, 2019)
      In this work, series of IrO2-Ta2O5 anodes were investigated. The catalytic activity towards oxygen evolution reaction (OER) of these anodes are determined by calcination temperature, coating loading (coating thickness), ...
    • The IrO2-Ta2O5 Coated Titanium Anode for Oxygen Evolution Reaction in Sulfate Solution 

      Xu, Wenting (Doctoral theses at NTNU;2018:320, Doctoral thesis, 2018)
      Titanium substrates coated with a conductive layer of metal oxides are well known gas evolving electrodes in the metal electrowinning industry, so-called dimensionally stable anodes (DSAs). DSA electrodes display better ...
