High purity TiFs was prepared by the thermal decor sition of arpmonium tetrafluorotitanate(III). TiF3 was prepared: m re easily by this: method than the previdusly rep rted ones. When titanium metal was dissolved in 55 wt% hydrofluoric acid in an argon atmospherc until hydrogen ev 1uti n stoPPed, the dar: k vi let precipitate was formed Ammonium tetrafluorotitanate(III)was formed by the addition of excess ammonium fluoride to the solution containing this precipitate. TiFs was easily prepared by the thermal decomposition of ammonium tetraflueretitanate (III)in a hydrogen or an arg n atmosphere at 600-650 C.<BR>Ammonium tetrafluorotitanate(III)colered yellowish pin: k and oxidized gradually in an air.
