High performance multicrystalline silicon: Grain structure and iron precipitation
Autruffe, Antoine; M'hamdi, Mohammed; Schindler, Florian; Heinz, Friedemann D.; Ekstrøm, Kai Erik; Schubert, Martin C.; Di Sabatino Lundberg, Marisa; Stokkan, Gaute (Peer reviewed; Journal article, 2017)A study of the spatial occurrence of iron precipitation in a high performance multicrystalline silicon (HPMC-Si) sample is presented. The separated effects of grain-boundaries, sparse intra-granular dislocations, and ... -
Recovery of Iron and Aluminum from Bauxite Residue by Carbothermic Reduction and Slag Leaching
Ekstrøm, Kai Erik; Bugten, Andreas Voll; Eijk, Casper van der; Lazou, Adamantia; Balomenos, E.; Tranell, Gabriella (Peer reviewed; Journal article, 2021)The recovery of major components of bauxite residue by carbothermic reduction at 1550–1750 °C and subsequent slag leaching in a Na3CO3(aq) solution is studied. Iron recovers primarily to pig-iron and lime is added to tune ...
