摘要：

The Tl2Te-Ag2Te system phase equilibria have been redetermined by DTA, X-ray diffraction and the measurement of thermoelectric power. The existence of the phase Tl2Te was first established and its crystallographic parameters were determined. At least four compounds are formed in the system. The crystallographic parameters of the congruently melting AgTlTe (483°C) and the incongruently melting AgTl3Te2 (382°C), Ag8Tl2Te5 (440°C) Ag5TlTe3 (446°C) and Ag9TlTe5 (504°C) were determined. The 0-50 mol% Ag2Te range of the system is non-quasi-binary and a narrow solid solution range around the AgTITe composition gives a new insight into its dimorphic transformation. © 1990.
