Doug,
We used commercially available alpha-Al2O3 (corundum) for the recent IUCr-CPD round
robin on quantitative phase analysis. The source details are :-
Bailalox alumina polishing powder
Baikowski International Corporation
Standard C 1.0 micron (scratch size - actual pa
Speaking of internal standards. Can someone recommend a source of bulk
alumina to use for production samples. I don't find 'linde A' listed in the
Buehler catalog anymore. I'm not sure which of the various grades they list
to order or if there is a better place to order it.

Excellent news! This amorphous standard issue has been driving me nuts.
When you say phase purity do you mean purity in terms of crystalline phase
content?
Yes.

Hi all,
This is to say that I'm am nearly finished with the re-certification of SRM
676 for amorphous content. The revised certificate, offering a discussion
as to the certification method, will be on the NIST website shortly, after
the review process is completed. The certified phase purity o
Analysis without internal standard (for example for bulk materials) can
be done with Maud for glasses of other common amorphous phases.

there is one example, plus a publication on line.

As previously mentioned many Rietveld programs will do what you want if
you're willing to do the amorphous content calculations by hand afterwards.
Some commercial software has it built in.
I've done work in this area, and there are some pitfalls of which you must
be aware, or your results

Many Rietveld programs will do so. For example, BGM
Probably the best approach is to include a known quantity of an internal
standard in the sample. Sample preparation is very important and you
will have to make sure the standard is carefully weighed and that the
mixiing procedure that is used is efficient. You can then carry out
quantitative Rietve
Dear all,
I have a powder diffraction of an amorphous multiphase material. I want to
do a quantitative analysis of the amorphous phase. Can anyone tell me what
software does it.
