THE METHOD OF PRODUCING SUBSTANTIALLY PURE METALLIC TITANIUM IN AN ELECTROLYTIC CELL WHICH COMPRISES: PREPARING A FUSED ELECTROLYTE CONSISTING ESSENTIALLY OF AT LEAST ONE HALIDE SALT OF THE GROUP CONSISTING OF ALKALINE EARTH METAL HALIDES AND MIXTURES OF ALKALINE EARTH METAL HALIDES WITH ALKALI METAL HALIDES, INTRODUCING SUBSTANTIALLY PURE TITANIUM MONOXIDE FREE FROM HIGHER OXIDES OF TITINIUM INTO THE SAID FUSED ELECTROYTE TO FORM A FUSED SALT CELL BATH, MAINTAINING THE FUSED SALT CELL BATH IN A FUSED STATE AT A TEMPERATURE NOT IN EXCESS OF 925* C. UNDER A NOBLE GAS ATMOSPHERE, PASSING AN ELECTROLYZING CURRENT THROUGH THE FUSED BATH BETWEEN AN ANODE AND A CATHODE IN CONTACT WITH SAID BATH AT A CELL VOLTAGE SUSH AS TO ESTABLISH A CATHODE CURRENT DENSITY WITHIN THE RANGE OF 1 TO 500 AMPERES PER SQUARE DECIMETER AND RECOVERING THE RESULTANT CATHODICALLY DEPOSITED TITANIUM.
