The influence of the second coordination sphere of titanium complexes on the charge transfer kinetics of the Ti (IV)/Ti (III) redox couple in melts of alkali metal halides was studied by cyclic voltammetry method. Diffusion coefficients in the CsC-CsF (10 wt. %) melt were calculated. The standard rate constants of charge transfer have been determined by the Nicholson method. The activation energies of the charge transfer process in (NaCl- KCl)equimol-NaF (10 wt. %) — K2TiF6, KCl-KF (10 wt. %) — K2TiF6 and CsCl-CsF (10 wt. %) — K2TiF6 melts were calculated.

The charge transfer kinetics for the redox couple Ti(IV)/Ti(III) in the KCl —KF (10 wt. %) —K2TiF6was studied by cyclic voltammetry method. The influence of strongly polarizing Mg2+, Ca2+, Sr2+and Ba2+cations on the kinetics of charge transfer for the Ti(IV)/Ti(III) redox couple upon their introduction into the initial melt, was studied. The activation energies of the charge transfer process for the initial melt and for the melt with the addition of alkaline earth metal cations were calculated.

The influence of the second coordination sphere on the electroreduction of hafnium complexes to hafnium metal, and the redox reaction Eu(III) + e⇔ ,Eu(II) in alkali halide melts was studied. It is shown that the large caesium cations in the melt reduce the transfer and the diffusion coefficients as well as the heterogeneous rate constants for charge transfer of hafnium complexes. The standard rate constants for the europium redox reaction increase when going from NaCl-KCl to CsCl. The different influence of the second coordination sphere on the electrode reactions is explained by different limitation stages for electron transfer.
