METHOD FOR PRODUCING Y2Ti2O5S2

Abstract: a method for producing ytios, including: placing sulfur, yo, tio, ys, and at least one flux selected from a halide of an alkali metal in a lower portion of a reaction vessel having an opening at an upper end; then vaporizing the sulfur and allowing the vaporized sulfur to react with yo, tio, and ysto obtain ytiosby heating the lower portion of the reaction vessel in a state where the opening of the reaction vessel is held upward and closed while an upper portion of the reaction vessel is not heated; and liquefying the vaporized sulfur in the upper portion of the reaction vessel to allow the liquefied sulfur to fall down and again vaporizing the liquefied sulfur in the heated lower portion of the reaction vessel, in which liquefaction and vaporization are repeatedly carried out, and allowing the vaporized sulfur to react with yo, tio, and ys.
