THE METHOD FOR PRODUCING ELEMENTAL TITANIUM WHICH COMPRISES REACTING TITANIUM TETRACHLORIDE WITH HYDROGEN AT A TEMPERATURE ABOVE 1000* K. TO REDUCE THE TITANIUM TETRACHLORIDE TO GASEOUS TITANIUM TRICHLORIDE, COOLING THE REACTION PRODUCTS TO A TEMPERATURE BELOW 900* K. TO LIQUEFT THE TITANIUM TRICHLORIDE WITHOUT CONCURRENT DISPROPORTIONATION THEREOF, INSOLATING THE LIQUEFIED TRICHLORIDE FROM THE OTHER REACTION PRODUCTS, THEREAFTER SUBJECTING THE LIQUEFIED TITANIUM TRICHLORIDE TO A TEMPERATURE BETWEEN 550* K. AND 750* K. TO EFFECT THE DISPROPORTIONATION THEREOF INTO GASEOUS TITANIUM TETRACHLORIDE AND SOLID TITANIUM DISCHLORIDE, SEPARATING THE TITANIUM TETRACHLORIDE FROM THE TITANIUM DISHCLORIDE, THEREAFTER SUBJECTING THE TITANIUM DISCHLORIDE TO A TEMPERATURE ABOVE 2000* K. TO EFFECT THE DISPROPORTIONATION THEREOF INTO ELEMENTAL LIQUID TITANIUM AND GASEOUS TITANIUM TRICHLORIDE, CONTINUOUSLY REMOVING THE TITANIUM TRICHLORIDE FROM THE VICINITY OF THE TITANIUM, AND THEN TAPPING THE LIQUID TITANIUM FOR THE SUBSEQUENT RECOVERY THEREOF IN INGOT FORM.
