    • Thermodynamic Behavior and Mass Transfer Kinetics of Boron Between Ferrosilicon and CaO-SiO2 Slag 

      Krystad, Egil Grøndal; Jakobsson, Lars Klemet; Tang, Kai; Tranell, Gabriella (Journal article; Peer reviewed, 2017)
      Equilibrium distribution and transport kinetics of boron between ferrosilicon and calcium silicate slag were investigated through experimental study. A 50 pct CaO-50 pct SiO2 slag (by weight) was held for different durations ...

    • Thermodynamics of Boron Removal from Silicon Using CaO-MgO-Al2O3-SiO2 Slags 

      Jakobsson, Lars Klemet; Tangstad, Merete (Journal article; Peer reviewed, 2018)
      Slag refining is one of few metallurgical methods for removal of boron from silicon. It is important to know the thermodynamic properties of boron in slags to understand the refining process. The relation of the distribution ...

    • X-ray Microprobe Investigation of Iron During a Simulated Silicon Feedstock Extraction Process 

      Bernardis, Sarah; Fakra, Sirine C.; Dal Martello, Elena; B. Larsen, Rune; Newman, Bonna K.; Fenning, David P.; Di Sabatino Lundberg, Marisa; Buonassisi, Tonio (Peer reviewed; Journal article, 2016)
      Elemental silicon is extracted through carbothermic reduction from silicon-bearing raw feedstock materials such as quartz and quartzites. We investigate the micron-scale distribution and valence state of iron, a deleterious ...
