THE PRODUCTION OF TITANIUM TRICHLORIDE BY ARC-INDUCED HYDROGEN REDUCTION OF TITANIUM TETRACHLORIDE

Finely powdered titanium trichloride of high purity was prepared by an arc-induced reaction of titanium tetrachloride with hydrogen. The hydrogen chloride by-product was passed over heated titanium, and the regenerated hydrogen and titanium tetrachloride were recirculated to the arc. The method in effect utilizes the reducing power of the titanium metal to produce titanium trichloride from titanium tetrachloride.
