摘要：In this paper LiF-CaF2 melt was selected as a supporting electrolyte, and K-2 TiF6 as an active species, Ti ion reduction process was investigated on a tungsten electrode by cyclic voltammetry(CV)and square wave voltammetry(SWV)at the temperature of 1100K. The results showed that there existed four reduction peaks and four corresponding oxidization peaks, which changed with K2 TiF6 content in the melt, they are redox couples of Ti4+/Ti3+,Ti3+/Ti2+ and Ti2+/Ti-0 as well as Ti3+/Ti-0 according to the electron transfer numbers calculated from the square wave voltammograms' results.
