The influence of the second coordination sphere on die 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 die large caesium cations in the melt reduce the transfer and the diffusion coefficients as well as the heterogeneous rate constants for charge transfer of harnitcn complexes. The standard rare constants for the europium redox reaction increase when going from NaCl-KCl to CsCl. The different influence of die second coordination sphere on the electrode reactions is explained by different limitation stages for electron transfer

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.
