Investigation of the phase barograms and diagrams of the GeI4-I2, GeI4-BiI3 and GeI4-HgI2 systems

The phase barograms of the systems GeI₄-I₂, GeI₄-BiI₃ and GeI₄-HgI₂ were determined by total pressure measurements in a membrane zero manometer and the resulting phase diagrams were compared with those obtained by DTA measurements. All the systems were single eutectics.

Zusammenfassung Durch Gesamtdruckmessungen mittels eines Membrannullmanometers wurden Phasenbarogramme der Systeme GeI₄-I₂, GeI₄-BiI₃ und GeI₄-HgI₂ ermittelt und die resultierenden Phasendiagramme mit den an Hand von DTA-Messungen erhaltenen verglichen. Alle diese Systeme besitzen einen eutektischen Punkt.
