The electrochemical de-oxidation process, also called FFC-Cambridge process, has been proposed previously for the production of reactive metals and their alloys through reduction of their metal oxides. The process works by introducing metal oxides into a molten salt bath where it is electrolysed to form metal powders offering both economic and environmental benefits over the traditional metal production methods.
Within the frame of the EU-financed project SCALE (GA 730105), SINTEF has optimized the parameters of the direct electrolytic reduction of Sc2O3 and Sc2O3-Al2O3 precursors (dross from Al-Sc alloy production), giving Sc and Al-Sc metallic powders, respectively, in a molten CaCl2-based electrolyte at a working temperature of ca. 900 °C. The influence of the cathode current collector, the electrode configuration and the applied cathodic potential in both the reduction mechanism as well as the metal product quality has been studied.
