Compaction of aluminium foil and its effect on oxidation and recycling yield
Vallejo-Olivares, Alicia; Philipson, Harald; Gökelma, Mertol; Roven, Hans Jørgen; Furu, Trond; Kvithyld, Anne; Tranell, Gabriella (Peer reviewed; Journal article, 2021)One of the problems when recycling aluminium is its oxidation and consequent metal loss. This is especially critical for the thin sheet/foil materials used for food packaging applications. Compacting the scrap into briquettes ... -
Continued study to aluminothermic reduction process for silicon production
Simkhada, Nishan (Master thesis, 2022)Hovedmålet med denne oppgaven var å undersøke effekten av understøkiometrisk reduksjonsmiddeltilsetning i silikabasert slagg under aluminotermisk reduksjonsprosess. Produksjon av Si med mindre Ca-innhold har vært et av ... -
Innovative Utilization of Aluminum-Based Secondary Materials for Production of Metallurgical Silicon and Alumina-Rich Slag
Philipson, Harald; Solbakk, Gjermund L.; Wallin, Maria; Einarsrud, Kristian Etienne; Tranell, Maria Gabriella (Journal article; Peer reviewed, 2022) -
Pilot-Scale Aluminothermic Production of Silicon Alloy and Alumina-Rich Slag
Zhu, Mengyi; Philipson, Harald; Blandhol, Kjell; Djupvik, Veronika; Engvoll, Krister; Safarian, Jafar; Tang, Kai; Gornerup, Mårten; Pastor Valles, Elisa; Wallin, Bogg Maria Elisabeth; Tranell, Maria Gabriella (Journal article; Peer reviewed, 2024)As global demand for silicon (Si) and alumina continues to surge, the significance of developing more sustainable production methods has intensified. The SisAl process represents a path-breaking approach to producing Si ... -
Silicon Production via Aluminothermic Reduction of Calcium Silicate Slags
Philipson, Harald (Doctoral theses at NTNU;2024:344, Doctoral thesis, 2024)Silicon is in high demand around the world, thanks to its essential role in everything from solar cells to silicones. But producing silicon is no small feat—it consumes a lot of energy and produces a significant amount of ... -
The effect of thickness and compaction on the recovery of aluminium in recycling of foils in salt flux
Philipson, Harald (Master thesis, 2020)I Norge förbränns mer än 40 000 ton aluminiumförpackningar årligen. Återvinning av denna mängd aluminiumförpackningar skulle spara 1,5 TWh energi och hundratusentals ton av koldioxidutsläpp. Det mycket svårare att återvinna ... -
The Effect of Varying CaO/SiO2 Ratios and Reductant Addition in Silicon Production by Aluminothermic Reduction of Silica Based Slags
Solbakk, Gjermund Lie (Master thesis, 2021)Målet med dette arbeidet var å se på hvordan forskjellige CaO/SiO2 forhold i slagger, samt hvordan forskjellige reduktant tilsatser påvirker aluminotermisk reduksjon av silika i nevnte slagger. SisAl Pilot prosjektet har ...
