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 O2− reacts with Ti^[3+] and Cl^− to form TiOCl(s). The concentration quotient of the equilibrium between titanium ions (Ti^[2+], Ti^[3+]) and metallic Ti, Kc, was revaluated at 740℃ as follows:3Ti^[2+]⇄2Ti^[3+]+Ti, Kc=8.0×10^[−2] mol L−1=1.2×10^[−1] mol kg^[−1]. In addition, the solubility product of TiOCl(s) in NaCl–KCl equimolar molten salt, Ksp, at 700℃ was determined using the results of absorption spectra, Ksp=1.2×10^[−2] mol^2 L−2=5.1×10^[−3] mol^2 kg^[−2]. |
