CHAPTER 20 METALLURGY AND THE CHEMISTRY OF METALS
... The trick in this process centers on the fact that TiCl4 is a liquid with a boiling point (136.4°C), a little higher than that of water. The tetrachloride can be formed by treating the oxide (rutile) with chlorine gas at high temperature. The balanced equation is: TiO2(s) + 2Cl2(g) → TiCl4(l) + O2(g ...
