Hi Venkat, If you mean to use rietveld on X-ray data I don't think you can get particle size distributions. X=ray data will give you an average crystallite size but this is not a distribution just an average. Also, it is crystallite size and the actual particles size can be different if the crystallites are agglomerated.
Have you considered trying dynamic light scattering? Cheers, Chris will > > > I am a new user of rietveld softwares.
