extraction of titanium - chemguide

Reduction of the titanium(IV) chloride. TiCl 4 can be reduced using either magnesium or sodium. AQA will accept either, and so I am just giving the magnesium one. Titanium(IV) chloride vapour is passed into a reaction vessel containing molten magnesium in an argon atmosphere, and the temperature is increased to about 1000°C.

Reduction of Metals (Extraction from Ore) - A-Level Chemistry

In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. It is possible to avoid this problem by first converting the ore to the chloride, and then reducing the chloride with a more reactive metal such as magnesium or sodium. This is the method used to extract titanium.
