    Notes: Abstract From phasebarograms it is possible to construct phase diagrams. We show on example of the system Bi/Se/O how follow ternary sections from the total pressure measurements in equilibrium and how we can attribute the barogram of the ternary region Bi2Se3/Bi2O2Se/Se to the binary system Bi2Se3/Se. The knowledge of the ternary system Bi/Se/I and its coexistent pressure courses allow to followT-p-x conditions for the chemical transport of phases from this system.

    Description / Table of Contents: Investigations on the Pseudobinary System Bi2Se3/BiCl3The phase diagram of the pseudobinary system Bi2Se3/BiCI3 was investigated by DTA, total pressure measurements and x-ray phase analysis. The two ternary phases BiSeCI and Bi8Se9CI6 melt incongruently at 395 and 540 degree, respectively. Heats of formation and standard entropies were calculated from vapor pressure data. The data see «Inhaltsübersicht».
    Notes: Aus den Ergebnissen von DTA-Untersuchungen, Gesamtdruckmessungen mit dem Membrannullmanometer und der Röntgenphasenanalyse wurde das Phasendiagramm des quasibinären Systems Bi2Se3/BiCl3 aufgestellt. Im System existieren die beiden ternären Phasen BiSeCl und Bi8Se9Cl6, die peritektisch bei 395 bzw. 540°C schmelzen. Die Auswertung der Koexistenzzersetzungsdruckfunktionen ergab die Bildungsenthalpien und Standardentropien: ΔH°B (BiSeClf,298) = -43,4 ± 1,5 kcal/mol.S° (BiSeClf,298) = 34,7 ± 2,2 cal/K · mol.ΔH°B (Bi8Se9Cl6,f,298) = -292,7 ± 6,0 kcal/mol.S° (Bi8Se9Cl6,f,298) = 269,7 ± 6,0 cal/K · mol.
