Abstract (en)
[origin: WO2007014422A1] A process for electrochemically reducing a titanium oxide in a solid state in an electrolytic cell that includes an anode, a cathode, a molten CaCl<SUB>2</SUB>-based electrolyte containing CaO, and titanium oxide feed material in contact with the molten electrolyte is disclosed. The process is characterised by controlling the process by controlling the concentration of CaO in the electrolyte.
