The solid-phase diagram of the Tl-TlBr-S system was clarified and the fundamental thermodynamic properties of Tl6SBr4 compound were studied on the basis of electromotive force (EMF) measurements of concentration cells relative to a thallium electrode. The EMF results were used to calculate the relative partial thermodynamic functions of thallium in alloys and the standard integral thermodynamic functions (-ΔfG0, -ΔfH0, and S0298) of Tl6SBr4 compound. All data regarding thermodynamic properties of thallium chalcogen-halides are generalized and comparatively analyzed. Consequently, certain regularities between thermodynamic functions of thallium chalcogen-halides and their binary constituents as well as degree of ionization (DI) of chemical bonding were revealed.

The work presents the results of a thermodynamic study of the Er-Te system by the method of electromotive forces (EMF) in the temperature range of 300-450 K. From the EMF measurements of the concentration cells relative to the Er and ErTe electrodes, the partial thermodynamic functions of ErTe and Er in the alloys are determined, based on which the standard thermodynamic formation functions and the standard entropies of the intermediate compounds ErTe3, Er2Te3, and ErTe are calculated. A comparative analysis of the obtained data with the literature is carried out.

The alloys of the Gd-Te system in the range of compositions > 75 at% Te were studied by the methods of X-ray diffraction (XRD) and electromotive forces (EMF). From the EMF measurements of the concentration cells relative to the GdTe electrode in the 300-450 K temperature range, the partial thermodynamic functions of GdTe in alloys were determined. By combining these data with the corresponding functions of Gd in GdTe, the partial molar functions of gadolinium in GdTe3+Te alloys, and standard thermodynamic functions of formation and standard entropy of the GdTe3 compound were calculated. The obtained results were compared with the literature data.

Infrared and Raman spectra of thiazole have been reinvestigated with new assignments of overtone and combination bands being proposed. Infrared spectra in the solid phase and in different solutions for 2-aminothiazole and 2-amino-[2H2]-thiazole, as well as Raman spectrum of microcrystalline powder for 2-aminothiazole were also studied and a general assignment for all the observed bands have been proposed. The present assignment satisfies the isotopic product rule for i.r. fundamentals. On this basis thermodynamic functions have been computed.

The thermodynamic properties and characteristic phase diagrams of some sections in the Ag-Bi-Sn system were calculated. The thermodynamic functions, such as Gibbs excess energy, activity and enthalpy of formation, were calculated using the RKM model and compared with experimental data reported in the literature. Iso-activity diagrams for all three components at 900 K have been constructed. The calculated phase diagrams of the vertical sections Sn-AgBi, Ag-BiSn and Bi-AgSn, obtained using the ThermoCalc program, were compared and confirmed with the results of DTA measurements from the present work. .

Abstract EMF measurements were performed on a chemical cell containing a silver and a nitrate electrode. The systems NaNO3 + AgNO3 , LiNO3 + AgNO3, and pure AgNO3 were investigated in a temperature range of 240 °C to 310 °C and in the total concentration range permitted by the phase diagram. We found a linear dependence of the EMF on temperature. Six constants, characteristic for the investigated molten salts depending neither on composition nor on temperature, were determined by the analytical construction of the activity coefficients. Together with the analytically constructed excess molar Gibbs function, the excess molar entropy was calculated from calorimetric data in the literature.

Thermodynamic properties of Na in an equimolar Bi–Pb alloy were determined at 723 K for compositions of 0.0075 ≤ XNa ≤ 0.1000 from electromotive force measurements on Na metal concentration cells with a solid Na–β-Al2O3 electrolyte. A coulometric titration technique was used to electrochemically generate the Na metal in the Bi–Pb alloy. The results indicate that, as Na is added to Bi–Pb, the liquid becomes more associated and suggests complex species formation with an ionic character intermediate between those observed for the constituent binaries.

The thermodynamic properties of dilute NiO in Na2O•2SiO2 for XNiO < 0.0125 have been investigated in the temperature range 1073–1173 K by emf measurements using the electrochemical cell[Formula: see text]where NiO denotes a solution with Na2O•2SiO2. It was found that for XNiO < 0.003 the solutions obey Henry's law. The Henrian activity coefficients and the related dilute solution thermodynamic properties based on the solid NiO standard state are reported.
