  新型Y3Al2氢化物的可逆氢化/脱氢性能

  摘要：

  摘要 Y3Al2 的氢化物相，即 Y3Al2H6.5 和 Y3Al2H2.2 是新形成的。Y3Al2 在 373 K 和 3.0 MPa 的氢气下氢化成 Y3Al2H6.5，而 Y3Al2H6.5 在 0.1 MPa 的氦气下脱氢成 Y3Al2H2.2 高达 873 K。此外，Y3Al2H6.5 和 Y3Al2H2.2 之间的部分可逆氢化/脱氢反应首次在 Y-Al 系统中得到证实。

  A method of liquid-metal solution calorimetry has been applied for thermochemical research of intermetallic compounds in the Al-Y and Al-Y-Ni systems. Heats of dissolution for the following intermetallics: Al3Y; Al2Y; Al2Y3 and Al4YNi in liquid Al were measured with the help of a high-temperature isoperibol Calvet-type calorimeter. Using these values, standard molar enthalpies of formation for the listed compounds were calculated: Delta(f,298)H(m) degrees(Al3Y) = -185.6 +/- 7.2 kJ mol(-1); Delta(f,298)H(m) degrees(Al2Y) = -160.4 +/- 7.5 kJ mol(-1); Delta(f,298)H(m) degrees(Al2Y3) = -234.4 +/- 19.5 kJ mol(-1); Delta(f,298)H(m) degrees(Al4Y-Ni) = -361.5 +/- 12.0 kJ mol(-1) Comparisons have been made with some available experimental data and theoretical values calculated from the Miedema model with the help of parameters recommended in different papers.

  The isothermal section of the Y-Al-Sb ternary system at 800 K has been investigated mainly by powder X-ray diffraction (XRD) with the aid of differential thermal analysis (DTA), optical microscopy and scanning electron microscopy (SEM). It consists of 12 single-phase regions, 23 two-phase regions and 10 three-phase regions. The maximum solid solubility of Al in Y5Sb3 is about 27 at.%. No ternary compounds were found.
