The influence of strongly polarizing cations Mg, Ca, Sr, and Ba on the charge transfer kinetics of the redox couple Ti(IV)/Ti(III) is studied. The standard rate constants of charge transfer ( k ) for the Ti(IV)/Ti(III) redox couple in the (NaCl-KCl)-NaF (10 wt %)-KTiF melt upon the addition of the strongly polarizing cations into the starting melt are determined. The dependence of the charge transfer rate constants on the ionic potential of the cations is established. The activation energies of the charge transfer process are calculated for the fluoride complexes of the Ti(IV)/Ti(III) redox couple with the outer-sphere cations Mg, Ca, Sr, and Ba.
