Abstract
A process and apparatus for producing titanium metal is described herein. The process comprises generating an RF thermal plasma discharge using a plasma torch provided with an RF coil; reducing titanium tetrachloride to a titanium metal by supplying titanium tetrachloride and magnesium into the RF thermal plasma discharge; and collecting or depositing the titanium metal at a temperature not lower than the boiling point of magnesium chloride and not higher than the boiling point of the titanium metal.
