Abstract
A titanium halide or a mixture of titanium halides is reacted with an oxide-free sodium amalgam at a temperature below the boiling point of mercury, and metallic titanium is isolated from the reaction product. Titanium tetrachloride and sodium amalgam may be brought into contact, in the presence of an inert gas such as argon, at 300 DEG C., the amalgam having been first filtered through glass wool. After reaction, the products are filtered, preferably through a filter bed of powdered titanium. The sludge is then heated to drive off unreacted mercury and sodium, and the titanium metal sintered above the melting point of sodium chloride and below 1200 DEG C., e.g. at 950 DEG C., in the presence of the sodium chloride formed in the reaction. The titanium is then recovered by removing the salt by bleaching or by vacuum distillation. Titanium di- and tri-chlorides may also be used. The amalgam may contain 0.05-4 per cent of sodium.
