✦ Synopsis
The electrochemical reduction of Ti4 + ions in equimolar KCI-NaCl melts containing less K,TiFd (lwt %) on a Pt electrode, was studied at 973 K by means of linear sweep voltammetry, stationary current density-potential curve and ac impedance methods. It was found that the reduction of Ti4+ ions in the molten salts proceeded in the following four consequent steps: Ti4+ + e = Ti3+; Ti3+ + e = Ti*+ ; Ti2+ + 2e = Ti(Pt allov): Ti'+ + 2e = Ti(Dure). And according to ac impedance measurements, the electroreduction reactions we;; reversible or q&ire;ersible.
