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.
