Charge Transfer Kinetics of the Ti(IV)/Ti(III) Redox Couple in Chloride–Fluoride Melts

(Digital Presentation) Charge Transfer Kinetics of the Ti(IV)/Ti(III) Redox Couple in the Cesium Chloride-Cesium Fluoride Melt with Addition of Alkaline Earth Metal Cations

“…Electrochemical behavior of titanium in chloride-fluoride melts has been the object of numerous studies (4)(5)(6)(7)(8)(9)(10)(11)(12)(13). It was found that the reduction in chloride-fluoride melts of Ti(IV) complexes to metal proceeds in two successive stages: recharge of Ti(IV) to Ti(III) with the formation of a soluble product and further reduction of Ti(III) to Ti (6).…”

“…It was found that the reduction in chloride-fluoride melts of Ti(IV) complexes to metal proceeds in two successive stages: recharge of Ti(IV) to Ti(III) with the formation of a soluble product and further reduction of Ti(III) to Ti (6). In (7)(8)(11)(12)(13) the diffusion coefficients of Ti(IV) at different temperatures in melts of different composition were determined.…”

Charge Transfer Kinetics of the Ti(IV)/Ti(III) Redox Couple in the Cesium Chloride-Cesium Fluoride Melt with Addition of Alkaline Earth Metal Cations

“…In LiCl-KCl and NaCl-KCl melts the reduction of Ti(IV) occurs according to the following scheme Ti(IV) → Ti(III) → Ti(II) → Ti. [10][11][12][13] Whereas in fluoride 14,15 and chloride-fluoride [16][17][18][19][20][21][22][23][24][25][26][27][28][29] melts titanium reduction occurs in two stages and metal deposition can take place directly from trivalent titanium.…”

“…The most number of studies have been focused on the electrochemical behavior of titanium in chloride-fluoride melts. [16][17][18][19][20][21][22][23][24][25][26][27][28][29] It has been established that the process of electroreduction of Ti(IV) complexes to the metal proceeds in two consequent stages: recharge of Ti(IV) to Ti(III) with the formation of a soluble product and further discharge of Ti(III) to Ti. There are not too much data on kinetic parameters of titanium electroreduction in melts.…”

“…The present work is a part of systematic research to determine the charge transfer kinetics for the redox couples of refractory metals. [27][28][29][30][31][32] Earlier the effect of the alkaline Earth metals cations (Mg 2+ , Ca 2+ , Sr 2+ , Ba 2+ ) on the standard rate constants of charge transfer was determined for the Nb(V)/Nb(IV) and Cr(III)/Cr(II) redox couples in different alkali halide melts. 32 Experimental Electrochemical cell and salt preparation.-The studies were carried out in the temperature range 973-1123 K by cyclic voltammetry using a dynamic electrochemical laboratory "VoltaLab 40" (software "VoltaMaster 4").…”
