THE METHOD OF PRODUCING TITANIUM MONOXIDE FROM TITANIUM DIOXIDE BY REDUCTION WITH ELEMENTAL CARBON WHICH COMPRISES FORMING AN INTIMATE MIXTURE OF TITANIUM DIOXIDE WITH AT LEAST ONE-HALF MOL BUT NOT MORE THAN ONE MOL OF ELEMENTAL CARBON PER MOL OF TITANIUM DIOXIDE, HEATING THE MIXTURE TO A REACTION TEMPERATURE WITHIN THE RANGE OF ABOUT 1100* TO 1200* C., REMOVING THE EVOLVED CARBON MONOXIDE FROM THE REACTION ZONE SUBSTANTIALLY AS RAPIDLY AS IT IS FORMED WHEREBY THE PARTIAL PRESSURE OF CARBON MONOXIDE IS MAINTAINING DYNAMICALLY AT LESS THAN ONE ATMOSPHERE, MAINTAINING SAID REACTION TEMPERATURE AND SAID REDUCED PARTIAL PRESSURE OF CARBON MONOXIDE UNTIL SAID EVOLUTION OF CARBON MONOXIDE SUBSTANTIALLY CEASES, WHEREBY TITANIUM SESQUIOXIDE IS FORMED SUBSTANTIALLY FREE FROM OTHER OXIDES OF TITANIUM, THEREAFTER HEATING AN INTIMATE MIXTURE OF THE RESULTING TITANIUM SESQUIOXIDE WITH AN EQUIMOLAR QUANTITY OF ELEMENTAL CARBON TO A REACTION TEMPERATURE WITHIN THE RANGE OF ABOUT 1500* TO 1800* C., REMOVING EVOLVED CARBON MONOXIDE FROM THE REACTION ZONE SUBSTANTIALLY AS RAPIDLY AS IT IS FORMED WHEREBY THE PARTIAL PRESSURE OF CARBON MONOXIDE IS MAINTAINED DYNAMICALLY AT LESS THAN ONE ATMOSPHERE, MAINTAINING SAID REACTION TEMPERATURE AND SAID REDUCED PARTIAL PRESSURE OF CARBON MONOXIDE UNTIL THE EVOLUTION OF CARBON MONOXIDE SUBSTANTIALLY CEASES, AND RECOVERING THE RESULTING TITANIUM MONOXIDE PRODUCT.
