Revaluation of equilibrium quotient between titanium ions and metallic titanium in NaCl-KCl equimolar molten salt

摘要

In this study, the effect of oxide ion on the equilibrium between titanium ions and metallic titanium was investigated in NaCl-KCl equimolar molten salt. The soluble species containing Ti~(3+) and O~(2-) was not confirmed in the molten salt by absorption spectroscopy. The result of XRD for the solidified sample containing Ti~(3+) and O~(2-) implies that O~(2-) reacts with Ti~(3+) and Cl~ to form TiOCl(s).
