Abstract

In this study, we present crystallographic analyses of high-energy X-ray diffraction data on polycrystalline UO₂ up to the melting temperature. The Rietveld refinements of our X-ray data are in agreement with previous measurements, but are systematically located around the upper bound of their uncertainty, indicating a slightly steeper trend of thermal expansion compared to established values. This observation is consistent with recent first principles calculations.

Thermal expansion in UO 2 determined by high-energy X-ray diffraction

Impact of Controlled Storage Conditions on the Hydrolysis and Surface Morphology of Amorphous-UO₃

Journal Article Hanson, Alexa Brooke ; Schwerdt, Ian James ; Nizinski, Cody A. ; ... - ACS Omega

The hydration and morphological effects of amorphous (A)-UO₃ following storage under varying temperature and relative humidity have been investigated. This study provides valuable insight into U-oxide speciation following aging, the U-oxide quantitative morphological data set, and, overall, the characterization of nuclear material provenance. A-UO₃ was synthesized via the washed uranyl peroxide synthetic route and aged based on a 3-factor circumscribed central composite design of experiment. Target aging times include 2.57, 7.00, 14.0, 21.0, and 25.4 days, temperatures of 5.51, 15.0, 30.0, 45.0, and 54.5 °C, and relative humidities of 14.2, 30.0, 55.0, 80.0, and 95.8% were examined.

Structure determination of a complex tubular uranyl phenylphosphonate, (UO{sub 2}){sub 3}(HO{sub 3}PC{sub 6}H{sub 5}){sub 2}(O{sub 3}PC{sub 6}H{sub 5}){sub 2}{center_dot}H{sub 2}O, from conventional x-ray powder diffraction data

Journal Article Poojary, D M ; Cabeza, A ; Aranda, A G - Inorganic Chemistry

The three-dimensional structure of a complex tubular uranyl phosphonate, (UO{sub 2}){sub 3}(HO{sub 3}PC{sub 6}H{sub 5}){sub 2}(O{sub 3}PC{sub 6}H{sub 5}){sub 2}(O{sub 3}PC{sub 6}H{sub 5}){sub 2} {center_dot} H{sub 2}O, was determined ab initio from laboratory X-ray powder diffraction data and refined by the Rietveld method. The crystals belong to the space group P2{sub 1}2{sub 1}2{sub 1}, with {alpha} = 17.1966(2) {Angstrom}, b = 7.2125(2) {Angstrom}, c = 27.8282(4) {Angstrom}, and Z = 4. The structure consists of three independent uranium atoms, among which two are seven-coordinated and the third is eight-coordinated. These metal atoms are connected by four different phosphonate groups tomore »« less

In situ observation of thermal expansion of tetragonal C11b phase in Zr₂Cu_(1-x)Od_x alloys

Journal Article Xu, Min ; Ye, Y. Y. ; Morris, James R ; ... - Intermetallics

The C11b phase crystalline structure (structure type MoSi{sub 2}, space group I4/mmm) in the Zr{sub 2}Cu{sub (1-x)}Pd{sub x} (x = 0, 0.25, 0.5, 0.75 and 1) alloys was examined in situ using high temperature X-ray diffraction (HTXRD) and Rietveld refinement of the data obtained at a constant heating rate. While the cell volume increases with increasing Pd as expected by the larger atomic radii, the coefficients of thermal expansion (CTEs) do not follow a uniform trend. The bonding in the basal plane is more elastically rigid than along the c-axis for all compositions. The CTE is more anisotropic for Zr{submore »« less

U(UO[sub 2])(PO[sub 4])[sub 2], a new mixed-valence uranium orthophosphate: Ab initio structure determination from powder diffraction data and optical and X-ray photoelectron spectra

Journal Article Benard, P ; Loueer, D ; Dacheux, N ; ... - Chemistry of Materials; (United States)

A mixed-valence uranium phosphate, U(UO[sub 2])(PO[sub 4])[sub 2], has been synthesized through dry and wet chemical processes. The crystal structure has been solved ab initio from conventional monochromatic X-ray powder diffraction. The unit cell is triclinic (space group P1, Z = 2) with the cell dimensions a = 8.8212(4) [angstrom], b - 9.2173(5) [angstrom], c = 4772(3) [angstrom], [alpha] = 102.622(4)[degrees], [beta] = 97.748(4)[degrees], [gamma] = 102.459(5)[degrees], and V = 416.55(3) [angstrom][sup 3]. Initial positional parameters for two independent uranium atoms were obtained by solution of the Patterson map resulting from 509 integrated intensities. Phosphorus and oxygen atoms were localizedmore »« less
