Abstract

Cyclic voltammetry and square wave voltammetry were used to investigate reduction mechanism of Ti(IV) on the iron electrode surface in NaCl-KCl-NaF molten salt system. It indicated that the Ti(IV) ions were reduced to titanium metal by three steps, Ti(IV) → Ti(III) → Ti(II) → Ti, and the reduction process was irreversible process controlled by diffusion. The nucleation mechanism of titanium ions on pure iron electrode surface was determined to be an instantaneous nucleation process.
