Quantitative phase analysis of Mg:ZrO2 nanoparticles by Rietveld refinement method
AIP Conference Proceedings, 2014To quantify the structural phases of nanocrystalline ZrO2 doped with Mg ions of varying concentrations (3, 5, 10, 15 and 20%) and annealed at different temperatures. Magnesia doped zirconia was prepared by chemical co-precipitation method and annealed up to 1000°C.

Development of an Automatic, High-Throughput Structural Refinement Method Using Rietveld Analysis
ACS Combinatorial Science, 2019Automated structural analysis techniques are required to accelerate materials research. In this study, we developed an algorithm to automate Rietveld analysis, which is a method for crystal structure refinement using powder diffraction patterns. This algorithm features the repeated generation of a set of initial values, followed by one-shot refinement.

Structure refinement of the boron suboxide B6O by the Rietveld method
AIP Conference Proceedings, 1991The structure of the boron suboxide B6O has been refined by the Rietveld method applied on X‐ray powder diffraction data. The samples were prepared by hot pressing amorphous boron and B2O3 and the data was collected with a STOE‐diffractometer equipped with a position sensitive detector. The structure belongs to the α‐boron family and is closely related

Rietveld refinement and optical parameters of ZnO nanopowder synthesized by co-precipitation method
International Journal of Modern Physics B, 2022Zinc oxide (ZnO) nanopowder samples were prepared by using co-precipitation method, with varying parametric conditions. Rietveld refinement technique is used to study the structural properties of synthesized samples. XRD and UV spectroscopy techniques have been used to characterize the samples which resemble ZnO nanostructures.

Crystal structure refinement of Bi1−xNdxFeO3 multiferroic by the Rietveld method
Ceramics International, 2012Abstract The effect of Nd doping on Bi 1− x Nd x FeO 3 ( x = 0.0, 0.175, 0.20) multiferroics synthesized by chemical co-precipitation method has been investigated by Rietveld analysis of X-ray powder diffraction (XRD) data. The formations of the single-phase compounds were confirmed by XRD.

Preparation and Crystal Structure Refinement of Li4Mn5O12 by the Rietveld Method
Journal of Solid State Chemistry, 1995Well-crystallized Li{sub 4}Mn{sub 5}O{sub 12} powder has been prepared by heating a eutectic mixture of lithium acetate LiOAc and manganese nitrate Mn(NO{sub 3}){sub 2} at 700{degrees}C for 1-3 days in an O{sub 2} atmosphere. The Li and Mn content in the final products was determined from atomic absorption spectroscopy. The tetravalent manganese in the

Application of the Rietveld Method for Structure Refinement with Powder Diffraction Data
Advances in X-ray Analysis, 1980The object of the Rietveld method is to produce refined values of crystal structural parameters from powder diffraction data. Many materials of great interest can not be made available for study in single crystal form. This may be because it is not possible to prepare a single-crystal form at all (e.g., human tooth enamel) or because the single-crystal
