Full-profile search-match by the Rietveld method. [PDF]
J Appl Crystallogr, 2019 A new fully automatic search–match procedure based on a Rietveld full-pattern-fitting method is presented. The method does not rely on peak positions and permits not only phase identification but also a quantification of the phases and their gross ...

A necessary criterion for obtaining accurate lattice parameters by Rietveld method. [PDF]
Sci Rep, 2017 To obtain the lattice parameters accurately by the Rietveld method, the relationship between the lattice parameters and the peak-shift, which is the deviation in diffraction angle from the theoretical Bragg position, was studied. We show that the fitting

Structural Analysis of Interstratified Illite-Smectite by the Rietveld Method
Crystals, 2021 Rietveld method is a powerful tool in obtaining structural information of clay minerals by using of X-ray diffraction (XRD) patterns. However, the interstratified illite-smectites (I-S) show various stacking defects preventing the direct application of ...

Diffraction Line Profiles in the Rietveld Method [PDF]
Crystal Growth & Design, 2020 The present work traces the evolution of the modeling of the diffraction line profiles in the Rietveld method, starting from the early and most schematic description with Gaussian curves to the mos...

Physica Scripta, 2014 A summary is given of the development of an improved method to handle powder diffraction data. The resulting method, now called the Rietveld method, uses powder diffraction step-scanned intensities instead of integrated powder intensities. This enables the full use of the information content of a powder diagram.

Application of the Rietveld method to the analysis of anhydrous cement [PDF]
Cement and Concrete Research, 2011 X-ray powder diffraction allows direct measurement of the phase content in cement. More recently, whole pattern approaches such as the Rietveld method show an improvement in both within (repeatability) and between laboratory (reproducibility) precision.

Full quantitative phase analysis of hydrated lime using the Rietveld method
Cement and Concrete Research, 2012 Full quantitative phase analysis (FQPA) using X-ray powder diffraction and Rietveld refinements is a well-established method for the characterization of various hydraulic binders such as Portland cement and hydraulic limes.

Makara Seri Sains, 2011 This research presents the use of the Rietveld method to study the phase composition of cordierite (MG2AL4SI5O18) ceramics prepared from rice husk silica, after the samples were sintered at 1300, 1400 and 1500 °C.
