I would use any good single-crystal structure to model the pattern. Refine
cell params as necessary. I would use the NIST certificate as a starting
point, but not an end point.

Hi All,
I am trying to exclude the glass capillary from the weight percent calculations
in my Rietveld refinement. I modeled the glass capillary using a SiO2 CIF file
and made the crystallite size very small. The issue I am having now is that in
the weight percent calculation it is saying the g

Dear Claire,
Make the sum of the remaining crystalline weight percentages to be 100%.
This is a rough, but simple, calculation.
Alternatively, measure an empty capillary and correct the raw data of
your mixture for such scattering (taking
Hi all,
SRM 676a consisted of Baikowski CR1. This material is of a non-ideal
crystallite size distribution: quite broad with tales to large crystallites.
SRM 676b was custom made for us by Baikowski with a more uniform crystallite
size distribution in the 200 nm region. We are working on the
Hi Claire
It sounds like you're using the Hill/Howard algorithm for quantification.
You just need to not put the details of the SiO2 phase you're using into
the summation.
This is equivalent to removing the ~90% attributed to the capillary, and
renormalising to 100%
