  Phase equilibria in the Tb–Ti–Ge system at 1070 K

  摘要：

  Physico-chemical analysis techniques, including X-ray phase analysis, electron probe X-ray analysis, differential thermal analysis and metallographic analysis were employed in constructing the isothermal section of the Tb-Ti-Ge system at 1070 K. The formation of the following ternary intermetallic compounds were detected in the Tb-Ti-Ge system at 1070 K: TbTiGe thigh-temperature modification of CeFeSi structure type, space group P4/nmm, a = 0.4050(2) nm, c = 0.7652(3) nm: low-temperature modification of La2Sb structure type, space group I4/mmm, a = 0.4053(2) nm, c = 1.5293(3) nm) and Tb22...15Ti34...41Ge44 (Sm5Ge4 structure type, space group Pnma, a = 0.7019(1)...0.6889(5) nm, b = 1.3457(2)...1.332(1) nm, c = 0.7156(1)...0.755(1) nm). The TbGe3.5 compound belongs to the ThGe2 structure type (space group Cmmm, a = 2.0738(4) nm, b = 0.4043(1) nm, c = 0.3914(1) nm). The high-temperature modification of the Th2Ge3 compounds belongs to the ThSi2 structure type (space group I4(1)/amd, a = 0.4061(2) nm, c = 1.372(1) nm). (C) 1998 Elsevier Science S.A.

  A complete thermodynamic investigation of the Ge-Ti system was performed in this study. Seven samples were prepared by arc-melting the pure elements in order to check the literature data on phase diagram and enthalpy of formation of Ti5Ge3. The samples were annealed at certain temperatures for extended periods of time, and then quenched. Both the as-cast and annealed samples were examined by X-ray diffraction (XRD) analysis and scanning electron microscope (SEM) technology. The phase transformation temperatures were measured by differential thermal analysis (DTA). The measurement on enthalpy of formation for Ti5Ge3 was performed using the Kleppa-type HTRC with the calorimeter temperature set at 1100 +/- 2 degrees C. Based upon the literature data and current experimental results, the Ge-Ti system was critically assessed by means of CALPHAD approach. The calculated phase diagram and thermodynamic properties agree well with the literature data and the present experimental results. (C) 2011 Elsevier B.V. All rights reserved.

  The crystal structure of the RTiGe3 compounds (R = La, Ce and Pr) has been studied by X-ray powder diffraction methods, Rietveld refinement has been carried out on the La homologue. These compounds crystallise in the BaNiO3 prototype structure, hP10-P6(3)/mmc, also called the hexagonal perovskite (a = 6.300(1), c = 5,915(1) A for LaTiGeO. This seems to be the first example in which an intermetallic phase adopts such a structure type which can be considered as derived from the Ni3Sn type (anti) by a distortion of the lattice and the occupation (if the quasi-octahedral 2a site at the origin of the cell (0, 0, 0) by Ti. The composition, also confirmed by microprobe analyses, was found to be strictly 1:1:3 indicating that these are line compounds, forming very likely by a peritectoid reaction. The existence of homologous compounds has been established for the lighter rare earths La, Cc and Pr. Heat capacity and magnetisation data show that CeTiGe3 orders ferromagnetically with a Curie temperature of nearly 14 K. On the other hand a - ln T variation of the magnetic part of the resistivity below 300 K is consistent with that expected for single impurity Kondo behaviour, CeTiGe3 is thus an uncommon example of a ferromagnetic dense Kondo lattice.
