Abstract

The equilibrium between metallic titanium and titanium ions (Ti ²⁺, Ti³⁺) dissolved in LiCl-KCl melts and the influence of the electrolyte composition on the equilibrium were investigated. The accurate concentrations of titanium ions had been obtained based on a reliable approach for taking samples. Furthermore, accurate values of the equilibrium constants were calculated by the best-fitting method under the consideration of the TiOCl dissolution. The influence of the electrolyte composition on the equilibrium was evaluated by determining the equilibrium constant K_c between titanium metal and titanium ions in LiCl-KCl melts with different concentration of LiCl. It was shown that LiCl could affect the equilibrium and the K _c values decreased with the increase of concentration of LiCl.
