Abstract The electrochemical reduction of Ti4+ ions in equimolar KClNaCl melts containing less K2TiF6 (1wt%) on a Pt electrode, was studied at 973 K by means of linear sweep voltammetry, stationary current density—potential curve and ac impedance methods. It was found that the reduction of Ti4+ ions in the molten salts proceeded in the following four consequent steps: Ti4+ + e = Ti3+; Ti3+ + e = Ti2+; Ti2+ + 2e = Ti(Pt alloy); Ti2+ + 2e = Ti(pure). And according to ac impedance measurements… Expand

The influence of fluoride ions on the equilibrium between titanium ions and titanium metal in fused alkali chloride melts.
The results reveal that the equilibrium transferred to the right direction for the first reaction and the apparent equilibrium constant increased sharply, mainly because of the formation of coordination compounds: TiFi(3-i), and the Gibbs free energies for complex formation increased sharply.
