Abstract

Abstract

The physical properties of chloride molten salt are very important for the preparation efficiency of titanium tetrachloride produced by molten salt chlorination. To investigate the influence of changes in chloride-containing molten salt composition on the physical properties of molten salt systems, this study conducted the physical property tests including conductivity and viscosity on normal raw salt, foam salt and filtered molten salt. Furthermore, XRD analysis and chemical composition analysis were also performed. Based on the component ratios in actual production and chemical analysis results, an orthogonal experiment with three factors including FeCl₂, FeCl₃, and MgCl₂ : NaCl was designed to study the changes of physical properties of molten salt systems under different component ratios. The results indicate that the FeCl₂ content has the most significant effect on the conductivity of the molten salt system, with an increase of 5% FeCl₂ resulting in a 0.33 S/cm increase in overall molten salt conductivity. The FeCl₃ content has the greatest impact on the viscosity of the molten salt system, with the effect being most pronounced within the 10% to 15% range of its composition. Finally, utilizing a comprehensive scoring method, the optimal chlorinated component scheme for molten salt was determined to be CaCl₂ 4%, FeCl₂ 20%, FeCl₃ 5% and MgCl₂ : NaCl = 1 : 1.
