Chemical Vapor Transport of Solid Solutions. 19, Chemical Vapor Transport of Mixed Phases in the Systems Ga 2 S 3 /Ga 2 Se 3 By means of CVT methods using iodine as transport agent (950 → 800 °C) in the system Ga 2 S 3 /Ga 2 Se 3 mixed crystals could be prepared. The miscibility gap, given in the literature, could not be observed, but the phase transition between a monoclinic (Ga 2 S 3 ) and cubic (Ga 2 Se 3 ) phase. The powder diffraction patterns of the mixed phases with the compositions Ga 2 S 2,4 Se 0,6 und Ga 2 S 0,6 Se 2,4 can be indexed hexagonally. The transport process occurs congruently. Thermochemical calculations as well as mass spectrometric investigations show that GaI 3 (solid: Ga 2 S 3 ) and GaI/GaI 3 (Ga 2 Se 3 ) are the gaseous species, due to the transport process. A congruent transport of all mixed phases in this system could be observed.
