• Behavior of Al4C3 Particles During Flotation and Sedimentation in Aluminum Melts 

      Gökelma, Mertol; Aarnæs, Trygve Storm; Maier, Jürgen; F. Renkel, Maria; Ekstrøm, Kai Erik; Friedrich, Bernd; Tranell, Gabriella (Peer reviewed; Journal article, 2021)
      Al4C3 particles form during the primary production of aluminum via molten salt electrolysis due to the carbon solubility and direct contact between bath, metal, and carbon anodes. Additional Al4C3 may form during melt ...
    • Behaviour of Aluminium Carbide in Al-melts during Re-melting 

      Gökelma, Mertol; Aarnæs, Trygve Storm; Maier, Jürgen; Friedrich, Bernd; Tranell, Gabriella (Journal article; Peer reviewed, 2019)
      The presence of non-metallic inclusions in aluminium has become a more critical issue with increasing demands on surface quality and low final wall thicknesses of products. Aluminium carbide particles form during the primary ...
    • Removal of Aluminium Carbide from Liquid Aluminium 

      Aarnæs, Trygve Storm (Master thesis, 2018)
      Aluminium carbide (Al4C3) inclusions are a common type of impurity found in aluminium alloys. Currently aluminium carbide cannot be efficiently removed due to its small particle size and wetting properties. The small carbide ...
    • SiC formation and SiO reactivity of methane at high temperatures 

      Aarnæs, Trygve Storm; Tangstad, Merete; Ringdalen, Eli (Peer reviewed; Journal article, 2021)
      Methane (CH4) is a carbon source currently not in use in the production of silicon. Using a gaseous carbon source instead of conventional solid carbon sources presents an opportunity to rethink silicon production. Preliminary ...
    • Silicon carbide formation from methane and silicon monoxide 

      Aarnæs, Trygve Storm; Ringdalen, Eli; Tangstad, Merete (Peer reviewed; Journal article, 2020)
      Silicon carbide (SiC) formation plays an important role during the production of elemental silicon. SiC forms through a high temperature reaction between silicon monoxide gas (SiO) and carbon. Currently, the carbon sources ...
