  demonstrates that hydrogen (deuterium) isotherms for Pd and its alloys can be measured down to quite low temperatures opening up new possibilities for the characterization of these systems. Deuterium isotherms are determined in this research down to 233 K and to 218 K for the Pd 0.95 Rh 0.05 and Pd 0.90 Rh 0.10 alloys, respectively. At low temperatures and moderate pressures, Pd and its alloys absorb significantly

  摘要 这项研究表明，Pd 及其合金的氢（氘）等温线可以测量到非常低的温度，这为表征这些系统开辟了新的可能性。在本研究中，Pd 0.95 Rh 0.05 和 Pd 0.90 Rh 0.10 合金的氘等温线分别确定为 233 K 和 218 K。在低温和中等压力下，Pd 及其合金吸收的 H 或 D 比在 298 K 时明显更多。例如，在 218 K 和 ≈ 1 bar 时，Pd 0.90 Rh 0.10 合金吸收 D 高达 (D/Pd 0.90 Rh 0.10 ) ≈ 0.8，摩尔比，而该比率在 298 K 时 ≈ 0.70 (Sakamoto et al., 1994) [1]。在低温下达到平衡的速度相对较快，例如，在 218 K 时，Pd 与 D 2 的平衡建立在 ≈ 10 m 内。

  two-way approach. Nanosized powders of metastable solid solutions and two-phase palladium–rhodium mixtures were used to shorten the time required to equilibrate the system. The initial samples were prepared by decomposition of coordination compounds [Pd(NH 3 ) 2 Cl 2 ], [Rh(NH 3 ) 5 Cl]Cl 2 , [Pd(NH 3 ) 4 ] 3 [Rh(NO 2 ) 6 ] 2 and [Pd(NH 3 ) 4 ][Rh(NH 3 )(NO 2 ) 5 ]. The obtained phase diagram exhibits miscibility

  摘要 使用 X 射线衍射、扫描和透射电子显微镜重新研究了亚固相线区域的 Pd-Rh 相图。混合性边界处的真正平衡是通过双向方法实现的。使用亚稳态固溶体和两相钯-铑混合物的纳米级粉末来缩短平衡系统所需的时间。初始样品通过分解配位化合物 [Pd(NH 3 ) 2 Cl 2 ]、[Rh(NH 3 ) 5 Cl]Cl 2 、[Pd(NH 3 ) 4 ] 3 [Rh(NO 2 ) 6 ] 2和[Pd(NH 3 ) 4 ][Rh(NH 3 )(NO 2 ) 5 ]。所获得的相图显示出比通常接受的更宽的混溶间隙，溶解度的临界点在 58 at.% Rh 和 820 °C。

  According to the results of powder X-ray diffraction study of the complex salts of composition [M(NH3)(5)Cl][M'Cl-4] (M = Ir, Rh, or Co and M' = Pt or Pd), the anhydrous salts crystallize in the orthorhombic system (space group Pnma) and are isostructural to the [Ir(NH3)(5)Cl][PtCl4] complex studied previously. The unit cell parameters of the resulting salts were refined. The metal powders, which were obtained by thermal decomposition of these salts under an atmosphere of hydrogen, were studied by powder X-ray analysis.

• The role of Al on the thermodynamics of hydrogen absorption/desorption by some ternary Pd–M–Al alloys where M=Rh, Ni, Pt, Cr, Ag

  The solution of hydrogen and hydride formation in FCC substitutional solid solution Pd0.9Rh0.1-xAlx alloys have been examined. In contrast to some other Pd ternary alloys, a linear relation does not obtain between the H capacity and x for these alloys where the H capacity of the alloys is estimated from the H content of the steeply rising part of the isotherms in the hydride phase regions. A linear increase of the dilute phase H solubility with x for these Pd0.9Rh0.1-xAlN alloys does, however, obtain for these alloys. Although Pd-Rh binary alloys have wider plateaux than does Pd itself, small amounts of Al substituted into Pd0.85Rh0.15 or Pd0.80Rh0.20 alloys can reduce or eliminate the two phase regions, the plateaux; there is, however, not much effect on the dilute phase solubilities. For example, small amounts of Al substituted into the Pd0.85Rh0.15 or Pd0.80Rh0.20 alloys eliminate the plateaux. On the other hand, alloying Pd with Al to form binary alloys with X-Al =0.015 or 0.030 does not eliminate the plateaux which are present in these binary alloys up to X-Al=0.075 (323 K). Small amounts of Al substitution do not have such a dramatic effect on the plateau widths of the Pd0.90N0.10 and Pd0.80Ni0.20 alloys and similarly substitution of Al into Pd-Cr and Pd-Ag alloys does not introduce any dramatic effects.
