Preparation of Titanium tetraiodide:
1) From the elements, typically using a tube furnace at 425 °C. On the other hand, this reaction can be reversed to produce highly pure films of Ti metal.

Ti + 2 I₂ → TiI₄

2) Exchange reaction from titanium tetrachloride and HI.

TiCl₄ + 4 HI → TiI₄ + 4 HCl

3) Oxide-iodide exchange from Aluminium iodide.

3 TiO₂ + 4 AlI₃ → 3 TiI₄ + 2 Al₂O₃
