Abstract
Equilibrium phase diagrams for the CdTe-Sn and CdTe-Pb systems have been determined by means of differential thermal analysis, X-ray diffraction and microscopic examination.
The CdTe-Sn and CdTe-Pb systems can be considered as pseudobinary systems from results of X-ray experiment. Phase diagrams of these systems are simple eutectic type. Eutectic point of each system is determined as 232°C, 99.995 mol%Sn for the CdTe-Sn system and 327°C, 99.94 mol%Pb for the CdTe-Pb system. Eutectic compositions were determined by extrapolation of the liquidus equation of the dilute solution:
