A PROCESS FOR MAKING A CO-CRYSTALLIZED SALT CONSISTING ESSENTIALLY OF ALUMINUM TRICHLORIDE AND TITANIUM TRICHLORIDE AND BEING FREE OF ELEMENTAL ALUMINUM; SAID TITANIUM TRICHLORIDE BEING ASSOCIATED WITH THE ALUMINUM TRICHLORIDE IN THE MOLAR RATIO THREE MOLES TITANIUM TRICHLORIDE AND ONE MOLE ALUMINUM TRICHLORIDE, FROM AN INTIAL SOLVENTFREE MIXTURE OF FLAKE ALUMINUM, TITANIUM TETRACHLORIDE AND ALUMINUM TRICHLORIDE, WHEREIN THE RATIO BY WEIGHT OF THE TITANIUM TETRACHLORIDE TO THE ALUMINUM TRICHLORIDE IS NOT GREATER THAN 285:1 AND THE RATION OF TITANIUM TETRACHLORIDE TO ALUMINUM IS NOT GREATER THAN 175:1, HEATING THE MIXTURE TO 136*C. AND CONTINUING TO HEAT THEREAFTER UNDER REFLUX CONDITIONS AT ATMOSPHERIC PRESSURE UNTIL TITANIUM TRICHLORIDE STARTS TO FORM ADDING ADDITIONAL TITANIUM TETRACHLORIDE AND CONTINUING HEATING SAID REFLUXING MIXTURE UNTIL FORMATION OF THE CO-CRYSTALLIZED SALT IS COMPLETE.
