• Alumina scale composition and growth rate in distribution pipes 

      Haugland, Ingrid Bokn; Kjos, Ole Sigmund; Røyset, Arne Karstein; Vullum, Per Erik; Aarhaug, Thor Anders; Halstensen, Maths (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2019)
      Scaling in distribution pipes for secondary alumina is a major issue in aluminium smelters. The scale is formed inside the distribution pipes, and gradually reduces the cross section that is available for alumina transport. ...
