Cathodic potential measurements on Pt, Cu, Ti, Zn, and Al electrodes were carried out at various current densities in aqueous solution of (NH4)2TiF6. The solution contains the cations Ti4+, NH4+ and H+, and the anions TiF6−−, F− and OH− according to the following equations:<BR>(This article is not displayable. Please see full text pdf.) <BR>Though Ti4+ ions begin to be reduced at about −0.8 V (vs. S.C.E.), the potential where the titanium deposition becomes visible is less noble than −1.1∼−1.2 V. The mechanism of the electrodeposition of titanium is either the direct discharge of Ti4+ ions or the reduction of titanium ions of lower valency such as Ti3+ or Ti2+ to metallic titanium by active hydrogen, but since a simultaneous evolution of hydrogen with the deposition of titanium was observed, the mechanism could not be identified in the present experiments.
