Abstract

A method for measuring the liquid–liquid interfacial tension between coexisting phases in metal systems will be presented in detail. First experimental results for the Ga–Hg and Ga–Pb systems were obtained. Measurements in the Ga–Hg system were taken between the monotectic temperature (TM = 26.7 °C) and 63.1 °C and in the whole range of the miscibility gap in the Ga–Pb system. In addition experimental results for the densities of the coexisting phases in the Ga–Hg system and for the density difference between the coexisting phases in the Ga–Pb system were obtained.

Abstract

In der vorliegenden Arbeit wird eine Methode zur Messung der Grenzflächenspannung zwischen den flüssigen koexistierenden Phasen metallischer Entmischungssysteme detailliert vorgestellt. Erste experimentelle Ergebnisse wurden für die Systeme Ga–Hg und Ga–Pb erhalten. Für das System Ga–Hg wurden die Messungen in einem Temperaturbereich zwischen der monotektischen Temperatur (TM = 26,7 °C) und 63,1 °C durchgeführt. Für das System Ga – Pb erstreckten sich die Messungen aber den gesamten Bereich der Mischungslücke. Zusätzlich wurden experimentelle Resultate für die Dichten der koexistierenden Phasen im System Ga–Hg und die Dichtedifferenz zwischen den koexistierenden Phasen im System Ga–Pb erhalten.
