REFINEMENT OF THE PHASE DIAGRAM OF THE MnTe–In2Te3 SYSTEM

Abstract

The MnTe–In2Te3 system was re-investigated by DTA and XRD methods, and its phase diagram was constructed somewhat differently from the previously known ones. It was found that the system is characterized by the formation of the MnIn2Te4 compound congruently melting at 1025 K with a wide (49–67 mol% In2Te3) homogeneity region. This phase is in eutectic equilibrium (1015 K) with solid solutions based on lt-MnTe (lt – low temperature) and in peritectic equilibrium with solid solutions based on In2Te3. A comparative analysis of the results obtained with the literature data is carried out
