Phase equilibria in the CdTe-Ge system

The revision of the CdTe-Ge phase diagram was performed by DTA, microstructure and X-ray diffraction methods supplemented by optical and scanning electron microscopy combined with electron probe microanalysis. These methods were completed by appropriate thermodynamic calculations. The following equilibria have been established in the CdTe-Ge system: the monotectic line lies at 1347 ± 1K in the 4–83 mol.% Ge composition range; the Ge-rich eutectic is situated at 1197 ± 1K and 97.5 mol.% Ge. The maximum solid solubility of Ge in CdTe is less than 1 mol.% Ge.
