THE METHOD OF PRODUCING ALKALI-TITANIUM DOUBLE FLUORIDES IN WHICH THE TITANIUM HAS A VALENCE OF LESS THEN FOUR WHICH COMPRISES: FORMING A CHARGE CONSISTING ESSENTIALLY OF (1) AN ALKALI-METAL-TITANIUM FLUORIDE IN WHICH THE TITANIUM IS TETRAVALENT AND (2) AN OXIDE OF TITANIUM IN WHICH THE TITANIUM HS A VALENCE OF LESS THAN FOUR, IN WHICH THE RELATIVE PROPORTIONS OF SAID ALKALIMETAL TITANIUM DOUBLE FLUORIDE AND SAID TITANIUM OXIDE AE SUCH AS TO PROVIDE AT LEAST ONE ATOM OF LOWER VALENT TITANIUM AS OXIDE FOR EACH TWO ATOMS OF TETRAVALENT TITANIUM AS DOUBLE FLUORIDE; HEATING THE CHARGE TO A TEMPERATURE SUFFICIENT OT MELT AT LEAST ONE OF SAID CHARGE CONSTITUENTS AND WITHIN THE RANGE OF 700*C. TO 1150*C. UNDER AN ATMOSPHERE INERT WITH RESPECT TO SAID REACTANTS, AND RECOVERING FROM THE REACTION MASS AT LEAST ONE RESULTING ALKALI-METAL DOUBLE FLUORIDE IN WHICH THE TITANIUM HAS A VALENCE OF LESS THAN FOUR.
