Electrochemical Mechanism of Molten Salt Electrolysis from TiO2 to Titanium. [PDF]
Materials (Basel), 2022 Electrochemical mechanisms of molten salt electrolysis from TiO2 to titanium were investigated by Potentiostatic electrolysis, cyclic voltammetry, and square wave voltammetry in NaCl-CaCl2 at 800 °C. The composition and morphology of the product obtained at different electrolysis times were characterized by XRD and SEM.
