Abstract

TiS2 was reduced using molten salt electrolysis. At 1173 K in CaCl2-0.5mol% CaS melt, the concentration of sulfur initially decreased significantly. 0.043 mass% S was obtained when the stoichiometric electric charge Q0 was supplied, and 0.01 mass% S was achieved when Q = 4Q0. Only α-Ti was identified by XRD at Q ≥ Q0. Metallic Ti and its lower oxides were identified at Q = Q0, but no lower sulfide could be found. It is possible to achieve excellent sulfur removal to a minimum concentration at a larger Q, and the use of TiS2 is promising for a new process for titanium refining.
