    • Thermal Insulation Materials in Aluminum Electrolysis Cells 

      Luneng, Raymond (Doctoral theses at NTNU;2020:112, Doctoral thesis, 2020)
      Aluminum is produced by an energy intensive process known as the Hall-Héroult process, which has been developed extensively since it was first invented in 1886. Recent trends in the aluminum industry has been to strive for ...
    • Thermogravimetric Analysis of Thermal Insulating Materials Exposed to Sodium Vapor 

      Luneng, Raymond; Wang, Zhaohui; Ratvik, Arne Petter; Grande, Tor (Journal article; Peer reviewed, 2019)
      The bottom thermal insulating layer in aluminum electrolysis cells is normally well protected from chemical attacks by a refractory layer. However, autopsies of spent cathode lining have shown that sodium vapor may reach ...
    • Van der Waals density functional study of the energetics of alkali metal intercalation in graphite 

      Wang, Zhaohui; Selbach, Sverre Magnus; Grande, Tor (Journal article; Peer reviewed, 2014)
      We report on the energetics of intercalation of lithium, sodium and potassium in graphite by density functional theory using recently developed van der Waals (vdW) density functionals. First stage intercalation compounds ...
