Titanium

Titanium dioxide is thermally stable and very resistant to chemical attack. It cannot be reduced using carbon, carbon monoxide or hydrogen, and reduction by more electropositive metals is incomplete. If the oxide is converted into titanium(IV) chloride, however, a route to titanium becomes viable, as the chloride is more readily reduced.
