Phase equilibria and decomposition of solid solutions in the YbTe–SnTe–PbTe system

Phase equilibria in the YbTe–SnTe–PbTe system have been studied using differential thermal analysis, X-ray diffraction, scanning electron microscopy, and emf measurements on YbTe concentration cells. We have mapped out a number of vertical sections, the 400-K isothermal section of the YbTe–SnTe–PbTe phase diagram, and projections of its liquidus and solidus surfaces. The results demonstrate that the system is characterized by the formation of a continuous series of high-temperature solid solutions with a cubic structure (NaCl type), which undergo decomposition below ~1050 K. At room temperature, the YbTe solubility in the Sn1–xPbxTe solid solution system is ~33–35 mol %, whereas the extent of the YbTe-based solid solution series does not exceed 3 mol %.

Yb-Sn-Te ternary system

Phase equilibria in the Yb-Sn-Te ternary system were studied for the first time by physicochemical methods. Phase diagrams were constructed for the Yb-Sn binary subsystem and YbTe-SnTe, YbSn-SnTe, Yb5Sn3-YbTe, YbSn-YbSnTe2

Phase diagram of the YbTe-Sb2Te3-Bi 2Te3 quasi-ternary system

The phase equilibria in the YbTe-Sb2Te3-Bi 2Te3 quasi-ternary system were investigated by means of differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscope with energy disper

Ba2Ln1-xMn2Te5(Ln = Pr, Gd, and Yb; X = Ln vacancy): Syntheses, crystal structures, optical, resistivity, and electronic structure

Three new isostructural quaternary tellurides, Ba2Ln1-xMn2Te5 (Ln = Pr, Gd, and Yb), have been synthesized by the molten-flux method at 1273 K. The single-crystal X-ray diffraction studies at 298(2) K showed that Ba2Ln1-xMn2Te5 crystallize in the space group -C2/m of the monoclinic crystal system. There are six unique crystallographic sites in this structure's asymmetric unit: one Ba site, one Ln site, one Mn site, and three Te sites. The Ln site in the Ba2Ln1-xMn2Te5 structure is partially filled, which leaves about one-third of the Ln sites vacant (□) for Pr and Gd compounds. These structures do not contain any homoatomic or metallic bonding and can be charge-balanced as (Ba2+)2(Gd/Pr3+)2/3(Mn2+)2(Te2-)5. The refined composition for the Yb compound is Ba2Yb0.74(1)Mn2Te5 and can be charge-balanced with a mixed valence state of Yb2+/Yb3+. The crystal structures of Ba2Ln1-xMn2Te5 consist of complex layers of 2∞[Ln1-xMn2Te5]4- stacked along the [100] direction, with Ba2+ cations separating these layers. The Ln atoms are bound to six Te atoms that form a distorted octahedral geometry around the central Ln atom. Each Mn atom in this structure is coordinated to four Te atoms in a distorted tetrahedral fashion. These LnTe6 and MnTe4 units are the main building blocks of the Ba2Ln1-xMn2Te5 structure. The optical absorption study performed on a polycrystalline Ba2Gd2/3Mn2Te5 sample reveals a direct bandgap of 1.06(2) eV consistent with the DFT study. A semiconducting behavior was also observed for polycrystalline Ba2Gd2/3Mn2Te5 from the resistivity study. The temperature-dependent magnetic studies on a polycrystalline sample of Ba2Gd2/3Mn2Te5 did not reveal any long-range magnetic order down to 5 K. The effective magnetic moment (μeff) of 10.37μB calculated using the Curie-Weiss law is in good agreement with the theoretical value (μcal) of 10.58μB.

THERMODYNAMICS OF VAPORIZATION OF SAMARIUM(II) TELLURIDE AND YTTERBIUM(II) TELLURIDE: A DISCUSSION OF THE THERMOCHEMISTRY OF THE DIVALENT LANTHANOID AND ALKALINE EARTH TELLURIDES.

The congruent vaporization of the solid monotellurides of ytterbium and samarium, both of practically stoichiometric composition, was studied over the temperature ranges 1606-1764 and 1732-1922 K, respectively, by the Knudsen effusion weight-loss technique. Using enthalpy and entropy data from the literature for gaseous LnTe, Ln, Te//2, and Te, and estimated data for solid LnTe(Ln equals Yb, Sm) it could be concluded from thermodynamic calculations that within the given temperature ranges-Ln and Te are the principal vapor species and that less than equivalent to 2. 8 and less than equivalent to 0. 9 mol percent of the vapor is present as YbTe and SmTe, respectively.
