متن کاملCubic ZrW1.75Mo0.25O8 from a Rietveld refinement based on neutron powder diffraction data
The solid solution in the system Zr-Mo-W-O with composition ZrW(1.75)Mo(0.25)O(8) (zirconium tungsten molybdenum octa-oxide) was prepared by solid-state reactions as a polycrystalline material. Its structure has cubic symmetry (space group P2(1)3) at room temperature. The structure contains a network of corner-sharing ZrO(6) octa-hedra (.3. symmetry) and MO(4) (M = W, Mo) tetra-hedra (.3. symme...
متن کاملA Rietveld refinement method for angular- and wavelength-dispersive neutron time-of-flight powder diffraction data
This paper introduces a two-dimensional extension of the well established Rietveld refinement method for modeling neutron time-of-flight powder diffraction data. The novel approach takes into account the variation of two parameters, diffraction angle 2θ and wavelength λ, to optimally adapt to the varying resolution function in diffraction experiments. By doing so, the refinement against angular...
متن کاملRietveld refinement of KLaTiO4 from X-ray powder data
Potassium lanthanum titanate(IV), KLaTiO(4), has been synthesized by conventional solid-state reaction. It crystallizes isotypically with the NaLnTiO(4) (Ln = La, Pr, Nd, Sm, Eu, Gd, Y and Lu) family. Five of the six atoms in the asymmetric unit (one K, one La, one Ti and two O atoms) are situated on sites with 4mm symmetry, whereas one O atom has 2mm. site symmetry. The crystal structure can b...
