  Structural characterization of NdNi(1−x)Cux compounds

  摘要：

  Phase transformations and crystal structures in the ternary compounds NdNi(1-x)Cux were examined with x parameter variation from 0 to 0.3 using X-ray diffraction on powders and single crystals. Three phases were characterized: an orthorhombic CrB type for x values between 0 and 0.175, a new monoclinic variant of the CrB type for x values ranging from 0.175 to 0.20, an orthorhombic FeB type for x values larger than 0.20. The unit cell parameters of the monoclinic variant (space group Pm, Z = 16, a = 7.603(1), b = 8.732(4), c = 11.146(3) Angstrom, beta= 109.91(2)degrees) are related to the orthorhombic CrB type parameters by the relations a(m) = 2a, b(m) = 2c, c(m) = b - a.

• Effect of sintering conditions on the formation of single-phase NdMgNi4 compound and its hydrogen storage properties

  Effects of different sintering conditions on the formation of single-phase NdMgNi4 compound and its electrochemical properties have been investigated. XRD analysis shows that an ideal single-phase compound of NdMgNi4 can be synthesized by sintering the pressed tablets of mixture of Mg, Ni and NdNi powders under 973 K for 5 h; single-phase compounds of REMgNi4 (RE = La, Ce, Pr) can be synthesized in this way as well. The electrochemical properties were measured by simulated battery tests. The maximum discharge capacity of NdMgNi4 compound was about 200 mAh/g, and just 78 mAh/g for CeMgNi4 compound. NdMgNi4 compound could store 3.5 H/M of hydrogen under 2.5 MPa at 298 K, whilst it is difficult to absorb hydrogen at a higher temperature (473 K). (c) 2006 Published by Elsevier B.V.
• The influence of Mg substitution on the phase structure and electrochemical properties of Nd1−Mg Ni3 (x = 0.10–0.50) alloys

  In this paper, Nd1-xMgxNi3 (x = 0.10-0.50) alloys as anode electrode materials of nickel metal hydride batteries were prepared by the powder sintering method. The solid solubility of Mg and electrochemical properties of the Nd1-xMgxNi3 (x = 0.10-0.50) alloys were studied. It is found that when x increases from 0.1 to 0.36, the multiphase structure with Ce2Ni7-, PuNi3- and MgCu4Sn-type phases of the alloy changes to PuNi3-type single-phase structure. As x further increases to 0.5, the extra Mg can not further enter into the PuNi3-type structure and forms an MgNi2 secondary phase. It indicates that the maximum solid solubility of Mg in the PuNi3-type (Nd, Mg)Ni-3 phase is 0.36 at 1183 K. Electrochemical studies show the PuNi3-type single-phase Nd0.64Mg0.36Ni3 alloy exhibits good discharge capacity, close to 341 mAh g(-1), and superior high rate dischargeability, which remains 151 mAh g(-1) at a current density of 1800 mA g(-1), respectively. Especially, the single-phase alloy exhibits excellent cycling property, which 288 mAh g(-1) retained after cycling 100 cycles. The content of Mg is a key factor that affects the phase structure and electrochemical properties for NdeMgeNi-based alloy. Less than or more than the maximum solid solubility value of Mg are disadvantageous to the cycling stability of the alloy due to the formation of impurity phase in the alloys. (C) 2015 Elsevier B.V.

• Study on phase formation mechanism and electrochemical properties of La0.75−xNdxMg0.25Ni3.3 (x=0, 0.15) alloys prepared by powder sintering

  An investigation of the phase formation mechanism and electrochemical properties of the La0.75-xNdxMg0.25Ni3.3 (x = 0, 0.15) alloys has been conducted in this paper. As explored by Rietveld analysis of the XRD data, the La0.75Mg0.25Ni3.3 alloy is composed of Ce2Ni7-type and Gd2Co7-type phases accompanied by minor CaCu5-type phase. The partial substitution Nd for La benefits the formation of Gd2Co7-type phase, indicating that the atoms with smaller radius favor the formation of the Gd2Co7-type phase. However, CaCu5-type phase disappears with Nd substitution. Because part of the replaced La atoms transform into [A(2)B(4)] subunits with the Ni atoms, and the formed [A(2)B(4)] subunits crystallize with [AB(5)] subunits to produce A(2)B(7)-type phase, resulting in the depletion of the minor CaCu5-type phase. The electrochemical P-C isotherms present that the La0.60Nd0.15Mg0.25Ni3.3 alloy only containing A(2)B(7)-type phase has one single plateau while the La0.75Mg0.25Ni3.3 alloy which contains minor LaNi5 phase has two plateaus. It is beneficial for the elevation of equilibrium plateau pressure ascribing to the contraction in cell volumes by Nd substitution. Electrochemical measurements show that the substitution of La by Nd improves the discharge capacity and the high rate dischargeability owing to the increase of A(2)B(7)-type phase abundance.

  The isothermal sections of the Nd-Mg-Ni ternary phase diagram at 1123 and 673 K (Ni-rich part) were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and differential thermal analysis. The 1123 K isothermal section consists of 8 single-phase regions, 14 two-phase regions and 7 three-phase regions. The 673 K isothermal section consists of I I single-phase regions, 21 two-phase regions, and I I three-phase regions. In addition, the existence of two ternary compounds NdMg2Ni9 and NdMgNi4 has been confirmed, and the Nd2MgNi9, Nd5Mg2Ni23 and Nd3MgNi14 compounds do not exist at 1123 and 673 K isothermal sections. No solid solubility was observed in our work. (c) 2006 Published by Elsevier B.V.
