“…The procedure for assembling an electrochemical cell and measuring the EMF is detailed in [24,25]. EMF measurements were carried at the 300-380 K temperature interval using a high-resistance digital voltmeter "2100 6 1/2 Digit Multimeter" (Keithley).…”

“…One of the well-reasoned ways of obtaining such data sets is associated with the use of the EMF method, which allows coordinating the study of phase equilibria and thermodynamic properties [21][22][23]. Similar complex studies were carried out by various modifications of the EMF method [24][25][26][27]. Particularly, the EMF method with solid Cu + conducting electrolyte is successfully applied to the thermodynamic study ternary and more complex copper-based chalcogenide systems [24,[28][29][30][31].…”

Fundamental thermodynamic properties of the synthetic analog of the famatinite mineral - Cu3SbS4 were studied on the basis of electromotive force (EMF) measurements. The EMF of the concentration chains relative to the Cu electrode with a solid electrolyte was measured for the alloys from the Cu3SbS4 + Sb2S3 + S phase region at 300-380K temperature interval. Based on measurement data, the relative partial thermodynamic functions of copper in alloys, the standard thermodynamic functions of formation, as well as, the standard entropy of the Cu3SbS4 ternary compound were calculated for the first time.

Equilibrium phase formations below 600 K in the parts Ag2Te–FeTe2–F1.12Te–Ag2Te and Ag8GeTe6–GeTe–FeTe2–AgFeTe2–Ag8GeTe6 of the Fe–Ag–Ge–Te system were established by the electromotive force (EMF) method. The positions of 3- and 4-phase regions relative to the composition of silver were applied to express the potential reactions involving the AgFeTe2, Ag2FeTe2, and Ag2FeGeTe4 compounds. The equilibrium synthesis of the set of phases was performed inside positive electrodes (PE) of the electrochemical cells: (−)Graphite ‖LE‖ Fast Ag+ conducting solid-electrolyte ‖R[Ag+]‖PE‖ Graphite(+), where LE is the left (negative) electrode, and R[Ag+] is the buffer region for the diffusion of Ag+ ions into the PE. From the observed results, thermodynamic quantities of AgFeTe2, Ag2FeTe2, and Ag2FeGeTe4 were experimentally determined for the first time. The reliability of the division of the Ag2Te–FeTe2–F1.12Te–Ag2Te and Ag8GeTe6–GeTe–FeTe2–AgFeTe2–Ag8GeTe6 phase regions was confirmed by the calculated thermodynamic quantities of AgFeTe2, Ag2FeTe2, and Ag2FeGeTe4 in equilibrium with phases in the adjacent phase regions. Particularly, the calculated Gibbs energies of Ag2FeGeTe4 in two different adjacent 4-phase regions are consistent, which also indicates that it has stoichiometric composition.

“…Taking this into account, we undertook a comprehensive study of phase equilibria and thermodynamic properties of the GeTe-Bi2Te3-Te system by the method of electromotive forces (EMF). Various modifications of this EMF method with liquid [30][31][32][33][34][35][36] and solid [36][37][38][39][40][41] electrolytes are successfully used to study chalcogenide systems.…”

The GeBi2Te4-Bi2Te3-Te system was investigated by XRD and EMF measurements of the reversible concentration cell of the type (-) GeTe (solid) │glycerol +KCl │ Ge-Bi-Тe (solid) (+) in the 300-450K temperature range. It was shown that, in the indicated temperature range, elementary tellurium forms tie lines with all telluride phases of the system. Equations for the temperature dependencies of EMF in all phase regions have been obtained from the data of EMF measurements, from which the partial thermodynamic functions of GeTe in alloys have been calculated. The partial molar functions of germanium in alloys were determined by combining obtained data with the thermodynamic functions of GeTe. Standard Gibbs free energy and enthalpy of formation, as well as the standard entropy of the GeBi2Te4, GeBi4Te7, GeBi6Te10 compounds and solid solutions based on Bi2Te3 have been calculated using these data, solid-phase equilibrium diagram of the GeBi2Te4-Bi2Te3-Te system, and corresponding thermodynamic functions of Bi2Te3.
