Rietveld Structure Refinement of Cu-Trien Exchanged Nontronites [PDF]
, 2018 The Rietveld analysis of X-ray powder diffraction patterns is used widely for obtaining the structural information of clay minerals. However, the complex hydration behavior and the variability of interlayer contents are often considered difficult to be ...

Rietveld refinement using Debye-Scherrer film techniques
, 1996 The advent of modern diffractometers has overcome the old film techniques that were used during the past years. One reason is that computer-controlled diffractometers made available data in a formal ready for the analyses, and the intensities obtained do

The validity of the Rietveld method
, 1983 The values of the estimated standard deviations given by the Rietveld profile refinement method are formally invalid, since the method does not take into account systematic errors which are introduced into the residuals by the constraints of the model ...

The estimation of standard deviations in powder diffraction Rietveld refinements
, 1983 It is shown that when the observed and calculated intensities in a powder diffraction pattern differ because of model errors which affect the calculated integrated intensities, in addition to the random counting errors, Rietveld refinement with weights ...
