Rietveld analysis on layer silicates

[Roger Mason]

Hi,

I am interested in doing Rietveld work on layer silicates (especially
pyrophyllite at the moment). I anticipate that there may be some problems
in dealing with stacking disorder and different kinds of ordered stacking
sequences when developing a structural model for analysis.

Being new to Rietveld I am wondering if anyone has worked on this problem.

Thanks,

Roger Mason
