Abstract

There is provided a titanyl sulfate hydrate powder comprising 25 to 40% by mass of titanium element in terms of TiO, 40 to 60% by mass of sulfur element in terms of HSO, and niobium element in such an amount that a molar ratio of niobium element to titanium element (Nb/Ti) is 0.00005 to 0.012, with a molar ratio of the sulfur element content to the titanium element content (S/Ti) being 1.1 to 1.5, and comprising crystalline titanyl sulfate dihydrate (TiOSO·2HO). Thus, the present invention can provide a titanyl sulfate hydrate powder with a high dissolution rate in water and a production method therefor, as well as a method for producing an aqueous titanyl sulfate solution, a method for producing an electrolyte and a method for producing a redox flow battery, using the titanyl sulfate hydrate powder.
