Abstract (en)
[origin: WO0073210A1] The invention concerns novel rare earth fluorosulphides using four modes of production, novel rare earth oxyfluorosulphides, their preparation methods and their use as dyeing pigment. The fluorosulphide of the first mode corresponds to the formula (LnSF) (Ln represents a rare earth) and has a particle average size of more than 5 mu m. That of the second mode is a mixed rare earth fluorosulphide of formula (Ln, Ln')SF and in the form of a solid solution. The fluorosulphide of the third mode, in a first embodiment, comprises at least an alkaline element and has a LnSF-type structure, the rare earth being selected among yttrium and from the group ranging from lanthanum to erbium inclusively. In a second embodiment of said third mode, the fluorosulphide comprises at least an alkaline element, it has a space group hexagonal structure P6>3<22, the rare earth likewise belonging to the group ranging from holmium to lutetium inclusively, also including yttrium. The fluorosulphide of the fourth mode corresponds to the formula Ln>2<AF>4<S>2< wherein A is an alkaline-earth. The oxyfluorosulphide corresponds to the formula Ln>3<S>2<F>3<O wherein Ln represents at least a trivalent rare earth.
