Abstract
The reaction between gaseous titanium tetrachloride and the eutectic melt of potassium and lithium chlorides was investigated at various temperatures and pressures. It was found that, at an optimum temperature of 370 °C, titanium tetrachloride vapor at a pressure of 1 atm reacts with the potassium chloride in the eutectic to yield K2TiCl6 as a solid mixture with lithium chloride.The solubilities of K2TiCl6, and the partial molar properties of the solutions of K2TiCl6, and of potassium chloride, in the eutectic melt of potassium and lithium chlorides were obtained by vapor pressure measurements. It was found that the solubility of titanium tetrachloride increases from 1.5 weight% at 420 °C to 5 weight% at 500 °C. The activities of K2TiCl6, and of potassium chloride, indicate positive deviations from ideality.Keywords
