ABSTRACT
The Ag-Tl-Te system was studied using the EMF method with a solid Ag+ conducting electrolyte Ag4RbI5 in the temperature range 295 450 K. Previously constructed solid phase diagram of this system was confirmed. The partial molar functions oDG ; DH ; DS P of silver in alloys, as well as the standard thermodynamic functions of formation and standard entropies of the AgTlTe2, AgTlTe, AgTl3Te2, Ag8Tl2Te5, Ag5TlTe3, and Ag9TlTe5 ternary compounds, were calculated. The received values were compared with the available literature data. The obtained results confirmed the possibility of the thermodynamic study of silver-containing complex systems using this modification of the EMF method, even if they contain a more electropositive metal than silver.
