  日期：2004.8

  The standard enthalpies of formation of some lanthanide silver compounds have been measured by high temperature direct synthesis calorimetry at 1373 +/- 2 K. The following results (in kJ/mol of atoms) are reported: 1: 1 composition-AgTb (-36.5 +/- 2.9); AgDy (-37.3 +/- 1.8); AgEr (-44.9 +/- 3.2); AgTm (-43.0 +/- 2.3); 2:1 composition-Ag2Pr (-24.7 +/- 1 1.6); Ag2Nd (-21.8 +/- 1.9); Ag2Gd (-23.9 +/- 1.6); Ag2Tb (-22.7 +/- 1.8); Ag2Dy (-22.3 +/- 2.3); Ag2Ho (-25.0 +/- 2.3); Ag2Er (-24.0 +/- 2.3); Ag2Tm (-24 +/- 3); Ag2Lu (-25.6 +/- 1.9); 3:1 composition-Ag3Tb (-20.6 +/- 2.0); Ag3Dy (-22.8 +/- 1.9); Ag3Ho (-25.1 +/- 2.0); Ag3Er (-25.4 +/- 2.3); Ag3Tm (-20.2 +/- 2.3). The results are compared with the semi-empirical predicted values of Miedema and coworkers and with the values predicted by Gschneidner for lanthanide alloys. They are also compared with the enthalpies of formation of the Au-LA systems by the present authors. (C) 2003 Elsevier B.V. All rights reserved.
• Interaction of the components in the Dy–Ag–Sn ternary system at 870 K

  The phase diagram of the Dy-Ag-Sn ternary system was constructed at 870 K using data of X-ray and partially metallographic analyses. Presence of the DyAgSn starmide in the system was confirmed (ST CaIn2, SG P6(3)/mmc, a = 0.46813(2), c = 0.73433(5) nm) and two new compounds were found: Dy3Ag4Sn4 (ST Gd3Cu4Ge4, SG Immm, a = 0.45316(1), b = 0.72887(2), c = 1.51225(5) nm) and DyAgSn2 (ST Cu3Au, SG Pm-3m, a = 0.453 10(l) nm). The DyAgSn2 is a Curie-Weiss paramagnet in the temperature range 80-470 K (mu(eff) = 10.64 mu(B), theta p = -14 K). A formation of substitutional solid solutions DyAg1-xSnx and DyAg2-xSn, was established. (c) 2006 Elsevier B.V. All rights reserved.
