Rietveld refinements of SnO2 ceramic powders doped with ZnO, WO3, CoO, Nb2O5 and MoO3
(2007-01-01)
Polycrystalline materials of SnO2 doped with ZnO, WO 3, CoO, Nb2O5, and MoO3. were synthesized by solid state reaction. X-ray powder diffraction data were collected with Cu Kα radiation from a Rigaku-Rint 2000 rotating ...
Rietveld analysis of mechanically activated BaCO(3)-TiO(2) system
(J C P D S-int Centre Diffraction Data, 2008-06-01)
BaTiO(3) powders were prepared through mechanical activation chemistry and analyzed by Rietveld refinement with X-ray diffraction data. Raw BaCO(3) and TiO(2) powders were dry milled for 5 and 20 h and then calcinated for ...

Synthesis and crystal structure refinement by th Rietveld method of an antimony-bearing titanite Ca(Ti0.6Al0.2Sb0.2)OSiO4
(Cambridge University Press, 2009-09)
A synthetic analogue, Ca(Ti0.6Al0.2Sb0.2)OSiO4, of antimony-bearing titanite of a composition similar to that found at St. Marcel-Praborna (Italy) was synthesized using ceramic methods and the crystal structure was refined ...
A whole pattern iterative refinement method for powder X-ray diffraction spectra of two-phase coherent alloys
(Springer, 2018-02)
An iterative refining method using FullProf software (Rietveld refinement) as a multi-input–output black-box with cyclic feedback is proposed in order to accurately measure the lattice misfit in two-phase coherent alloys. ...
Synthesis and crystal phase evaluation of hydroxylapatite using the rietveld-maximum entropy method
(2004-12-01)
Bioceramic systems based on hydroxylapatite (HAP) are an important class of bioactive materials that may promote bone regeneration. The aim of this research was to evaluate how the stoichiometry of HAP influences its ...
Characterization of nickel doped Zn7Sb2O12 spinel phase using Rietveld refinement
(J C P D S-int Centre Diffraction Data, 2003-09-01)
Zn7Sb2O12 is known to adopt an inverse spinel crystal structure, in which Zn2+ occupies the eight tetrahedral positions and Sb5+ and Zn2+ randomly occupy the 16 octahedral positions. Samples of Zn7-xNixSb2O12 (X = 0, 1, ...
