    Description / Table of Contents: Correlations between Properties of Chalcogenide Glasses. I. The System Germanium - Antimony - SulphurGlass formation and properties of the glasses in the system Ge-Sb-S are described. The limits of the glass-forming region correspond approximately to the lines joining GeS, GeS3 and Sb2S3 in the composition diagram. The results indicate two regions of liquid immiscibility, both at high sulphur and high antimony contents. The densities increase linearly with the average molecular weights per formula-unit of the glasses. Glass transition temperatures are in the range from 200 to 350°C, and values of Vickers hardness between 150 and 300 kp/mm2 have been measured. Both properties are in a linear relationship with the approximate values for the atomization energies of the glasses.
    Notes: Die Glasbildung im System Ge-Sb-S und die Eigenschaften der Gläser werden beschrieben. Der Glasbildungsbereich wird im Konzentrationsdreieck etwa durch die Geraden GeS-Sb2S3 und GeS3-Sb2S3 begrenzt; bei höheren Schwefel- bzw. Antimongehalten werden ausgedehnte Gebiete mit Mikro- und Makrophasentrennung beobachtet. Die Dichten der Gläser steigen proportional zur mittleren Molmasse der Formeleinheit. Die Transformationstemperaturen liegen bei 200 bis 350°C, die Mikrohärten zwischen 150 und 300 kp/mm2. Beide Größen lassen sich mit den näherungsweise errechneten Atomisierungsenthalpien der Gläser korrelieren.
