• C-TiB2 Composite Inert Cathode Material by Spark Plasma Sintering 

      Håberg, Audun (Master thesis, 2018)
      TiB2 has been considered a potential inert, wettable cathode material for aluminum reduction cells for a long time. An important characteristic of TiB2 as a cathode material, is its excellent wetting properties towards ...
    • Carbon cathode wear in aluminium electrolysis cells 

      Senanu, Samuel; Wang, Zhaohui; Ratvik, Arne Petter; Grande, Tor (Journal article; Peer reviewed, 2019)
      Autopsies of six spent potlinings with different carbon cathode block grades, amperage regimes and cell technologies were conducted at three separate smelters to reveal possible mechanisms causing cathode wear. Microstructure ...
    • Carbon Cathode Wear in Aluminium Electrolysis Cells 

      Senanu, Samuel; Wang, Zhaohui; Ratvik, Arne Petter; Grande, Tor (Peer reviewed; Journal article, 2019)
      Autopsies of six spent potlinings with different carbon cathode block grades, amperage regimes and cell designs were conducted at three separate smelters to reveal possible mechanisms causing cathode wear. The microstructure ...
    • Cathode Wear Based on Autopsy of a Shutdown Aluminium Electrolysis Cell 

      Senanu, Samuel; Schøning, Christian; Rørvik, Stein; Wang, Zhaohui; Ratvik, Arne Petter; Grande, Tor (Journal article; Peer reviewed, 2016)
      To investigate cathode wear, an autopsy of a shutdown aluminium electrolysis cell was conducted. The original lining consisted of a fully impregnated and graphitized carbon block and the cell was shut down after 2461 days ...
    • Cathode Wear in Aluminium Electrolysis Cells 

      Senanu, Samuel (Doctoral theses at NTNU;2019:317, Doctoral thesis, 2019)
      The increasing global demand for aluminium has resulted in growing production of aluminium metal through increased production capacity and improvement of the electrolysis technology. This has caused a development towards ...
    • Pitting on Carbon Cathodes in Aluminium Electrolysis Cells 

      Senanu, Samuel; Ratvik, Arne Petter; Grande, Tor (Journal article; Peer reviewed, 2018)
      Uneven cathode wear is one of the key challenges for the lifetime of aluminium electrolysis cells. Here we report on autopsy of several potlinings with focus on the surface morphology of the carbon cathodes. The surface ...
    • Role of Pitting in the Formation of Potholes in Carbon Cathodes - A Review 

      Senanu, Samuel; Grande, Tor; Ratvik, Arne Petter (Journal article; Preprint, 2016)
