The equilibrium between metallic titanium and titanium ions in LiCl-KCl melts

The equilibrium between metallic titanium and titanium ions (Ti2+, 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 Kc 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 Kc values decreased with the increase of concentration of LiCl.
