Crystal Structure of Al2Cu3Nd Ternary Compound
Materials Science Forum, 2016Co-Authors: Liu Qing Liang, Ming Qin, Chang Sheng Qin, Shu Hui Liu, Chen Zhong Jia, Ling Min ZengAbstract:A new Al-Cu-Nd system alloy, the high-purity Al2Cu3Nd Ternary Compound, was developed and prepared with the stoichiometric amounts of elemental constituents by arc melting under argon atmosphere. The X-ray diffraction (XRD) data of Al2Cu3Nd was collected by using the Rigaku Smart Lab X-ray powder diffractometer, and all X-ray diffraction peaks of Al2Cu3Nd Compound were indexed successfully with the hexagonal structure. The Rietveld refinement results of the XRD pattern for the Al2Cu3Nd Compound showed that the Al2Cu3Nd Compound is the hexagonal structure, space group P6/mmm (No.191) with a = 5.2397(1) A, c = 4.1783(1) A, V = 99.34 A3, Z = 1. The density of the Compound was 6.501 g/cm3, and its reference intensity ratio (RIR) w 1.26.

Journal of Alloys and Compounds, 2010Co-Authors: Ling Min Zeng, C Z Liao, Cheng Dong, W H Cao, Lihong YangAbstract:A new Compound MgNi7B3 in the Mg-Ni-B Ternary system was prepared by solid state reaction and its crystal structure was determined using X-ray powder diffraction data. The MgNi7B3 Compound crystallizes with ErNi7B3 structure type (space group I4(1)/amd, a = 7.4877(2) angstrom, c = 15.4879(4) angstrom, Z = 8.), and the Rietveld refinement of the crystal structure was performed which gave R-wp = 7.02%, R-p = 4.96%. The MgNi7B3 sample was characterized by magnetization and electric resistivity measurements. MgNi7B3 exhibits metallic behavior in the temperature range from 5 to 300 K and shows spin-glass-like behavior at low temperature with the spin freezing temperature (T-f) around 13 K.

Journal of Alloys and Compounds, 2013Co-Authors: E V Murashova, Yu. D. Seropegin, Zh M Kurenbaeva, A I Tursina, E V Marushina, A Yaroslavtsev, Denis Leshchev, D KaczorowskiAbstract:Abstract The intermetallic phase Ce 2 RuAl was synthesized by arc melting the elemental components and subsequent annealing of the product at 823 K. Its crystal structure was determined from the single-crystal X-ray diffraction data and confirmed by powder X-ray diffraction at room temperature. The Compound is of a new structural type related to the LaF 3 -type of structure: space group P 6 3 cm , Z = 6, a = 7.8362(7) A, c = 9.7510(9) A, Pearson symbol hP24 . Some Ce–Ru distances in the unit cell are unusually short being equal to 2.4821(6) A. This structural feature brings about instability in the cerium valence state, directly evidenced in the XANES data and corroborated in the study of bulk physical behavior in Ce 2 RuAl.
