Just few words of warning : think of preferred orienatation in your
samples... Moreover, from the vast majority of montmorilonites one gets
only few so
called "00L" diffractions what means that the results of quantitative
phase analysis can be better obtained by a random numbers generator :-)

I guess these differences in I/Ic are not very significant, since the
exact same montmorillonite entry is in I
Dear Mrs. Chrysochoou,
the cif-file below was created from the AMCSD (American Mineralogist Crystal
Structure Database) reference database by Match!, Crystal Impact's software
for phase identification from powder diffraction data. The I/Ic value
calculated by Match! is 20.5

Hi,
does anyone have a freely available structure file for montmorillonite (any
hydration state)? Also, what is a reasonable Reference Intensity Ratio for it?
The only ICSD entry has an RIR of over 23, so does vermiculite. Why is that so
high?
Thank you,
Maria Chrysochoou
