Abstract

The electrochemical behaviour of Ti⁴⁺ (K₂TiF₆) at liquid tin and bismuth electrodes has been investigated by cyclic voltammetry, square wave voltammetry and chronoamperometry in the LiF–NaF–KF eutectic melt. Result shows that, on the liquid metal electrodes, the reduction reaction of the solvent occurs at more positive potential than that on the inert molybdenum electrode. There are two reduction steps including Ti⁴⁺ + e = Ti³⁺ and Ti³⁺ + 3e = Ti (Ti–Sn alloys) on the liquid tin electrode within the electrochemical window of the melt. However, only one redox process corresponding to the redox of the Ti⁴⁺/Ti³⁺ couple is observed at liquid bismuth electrode.
