Meer informatieChemistry of Titanium
The titanium is produced by reacting titanium(IV) chloride, (ce{TiCl4}) - NOT the oxide - with either sodium or magnesium. That means that you first have to convert the oxide into the chloride. That in turn means that you have the expense of the chlorine as well as the energy costs of the conversion.
