Das System Arsen-Tellur. Dichten und elektrische Leitfähigkeiten der Schmelzen, Phasendiagramm / The System Arsenic-Tellurium. Density and Electrical Conductivity of the Melts, Phase Diagram

Abstract

The phase diagram of the system As—Te has been determined. The density and the electrical conductivity of the melts were measured as a function of temperature and concentration. The density increases with increasing temperature. The electrical conductivity has a minimum near 40 mol% As. This minimum becomes less pronounced with increasing temperature. Both observations indicate, that polymeric units exist in these melts, which are destroyed at higher temperature.
