An Introduction to the Chemistry of Metal Extraction

TiCl4 + 4Na → Ti + 4NaCl. The more reactive metal sodium releases electrons easily as it forms its ions: 4Na → 4Na + + 4e −. These electrons are used to reduce the titanium (IV) chloride: TiCl4 + 4e − → Ti + 4Cl −. The downside of this is expense. You have first to extract (or to buy) the sodium or magnesium.
