Phase equilibria in the Tl-TlCl-Te system and thermodynamic properties of the compound Tl5Te2Cl

The Tl-Te-Cl system was studied in the Tl-TlCl-Te composition region by differential thermal analysis, X-ray powder diffraction, and emf and microhardness measurements. A series of polythermal sec- tions, an isothermal section at 400 K, and a projection of the liquidus surface of the phase diagram were con- structed. The ternary compound Tl5Te2Cl characterized by a wide homogeneity region and incongruent melting by a syntectic reaction at 708 K was shown to exist. This compound was found to crystallize in tetragonal lattice (space group I4/mcm) with the parameters a = 8.921 ?, c = 12.692 ?, and Z = 4. Wide phase separation regions were also found in the system, including a three-phase separation region in the Tl-TlCl-Tl2Te sub- system. Regions of primary crystallization of phases, and the types and coordinates of in-and monovariant equilibria in the T-x-y diagram were determined. From emf measurement data, the standard thermody- namic functions of formation and the standard entropy were calculated for the compound Tl5Te2Cl, as follows: =ΔG0 298 355.9 ± 1.1 kJ/mol, =ΔH0298 377.1 ± 5.0 kJ/mol, andΔS0298 = 474.1 ± 6.8 J/(mol K).

Preparation, crystal structure, physical properties and electronic band structure of TlScQ2 (Q = S, Se and Te)

The title compounds were prepared by reaction of Tl2Q (Q = S, Se and Te) Sc and Q in the temperature range of 200 to 500 °C. The structures of the selenide and the telluride adopt the α-NaFeO2 type, while TlScS2 crystallizes in the β-RbScO2 type structure. The space group is R3m for TlScSe2 and TlScTe 2 with a = 3.9370(4) A, c = 23.194(5) A, and a = 4.2129(4) A, c = 24.099(3) A, respectively. The sulphide crystallizes in P63/mmc with a = 3.761(3) A and c = 14.942(4) A. The crystal chemical relations between the three chalcogenides are discussed. According to the electrical measurements and the band structure calculations, the compounds are semiconductors or poor metals.

Phase equilibria in the Tl-TlBr-Te system and thermodynamic properties of the compound Tl5Te2Br

The Tl-TlBr-Te composition region of the Tl-Te-Br phase diagram has been explored by DTA, X-ray diffraction, microhardness measurements, and electromotive force (emf) measurements relative to a thallium electrode in concentrations cells. The phase diagrams along a number of joins, the isothermal section at 400 K of the phase diagram, and a projection of the liquidus surface have been constructed. Extensive phase-separation areas, including a three-liquid-phase field in the Tl-TlBr-Tl2Te subsystem, have been revealed. The homogeneity ranges and primary crystallization fields of phases have been mapped, and the coordinates of nonvariant and univariant equilibria in the T-x-y diagram have been determined. The standard thermodynamic functions of formation of the Tl5Te2Br compound and its standard entropy have been derived from emf data.

Among a number of Tl//2X(X equals S, Se, Te)-type thallium chalcogenides the heat capacities of Tl//2Se and Tl//2S compounds have been studied and their thermodynamic parameters calculated. However, for Tl//2Te such data are lacking.

New thallium neodymium tellurides

The phase equilibria in the composition region Tl2Te-Tl 2Te3-Nd2Te3-NdTe of the Tl-Nd-Te system have been studied by differential thermal analysis and x-ray diffraction, and the 500-K section of its phase diagram has been mapped out. The ternary compounds identified are Tl9NdTe6, Tl4NdTe 3, Tl6Nd4Te9, Tl4Nd 6Te11, Tl2NdTe3, TlNdTe3, and TlNd3Te6. X-ray powder diffraction data indicate that the compounds Tl9NdTe6 and Tl4NdTe3 are structural analogs of Tl5Te3 and have tetragonal cell parameters a = 8.855 A, c = 13.010 A and a = 8.858 A, c = 12.998 A, respectively (sp. gr. I4/mcm, Z = 4). Tl9NdTe 6 and Tl4NdTe3 are phases of variable composition (δ-phase), and their fields cover most of the Tl 2Te-Tl5Te3-Tl4NdTe3 composition triangle. The structure of Tl5Te3 and its ternary analogs is discussed, and the conclusion is drawn that, in spite of the broad field of the δ-phase, Tl9NdTe6 and Tl 4NdTe3 are daltonides, i.e., distinct chemical compounds.
