Hi All
I know this doesn't have direct application to rietveld work (well, I will be
using it), but I am doing time-resolved powder XRD precipitation experiments in
hydrothermal aqueous solutions using 1mm OD sapphire capillaries, a furnace
mounted to our XRD and epoxy. I am curious whether
Dear All,
I was wondering if there are any advantages of using Rietveld vs Le Bail
refinements when crystallite size and cell parameters are the only
variables of interest?
Thank you,
Sergey

Hi !
I have worked with both methods in ZnO, I have found that it is easier
work with Le Bail or Pawley when you are looking for size strain and
lattice parameters, because you just need some data about the crystal
structure. But this is just an specific case.

Le-Bail and Pawley methods give extra freedom to intensities which may
lead to adverse correlations between peak intensities and shape
especially for noisy and overlapped data. In Rietveld refinement the
intensities are restrained by the structure model and the
instrument-related parameters, so if
