Brandon -
It is more important to get the make/model of the XRD instrument, to
know their sample size requirements. I am used to sample holders
35mm x 35mm x 3mm, which hold powder in a well/trough 15mm x
20mm x 1.5mm. For that particular instrument, the area of 15mm x
20mm is the most important, as the depth could be between zero and 7mm.
For bulk samples, we were limited to 45mm(W) x 80mm(L) x 7mm (T).
Another instrument I know limits this to 30mm(W) x 50mm (L) x 3mm (T).
You really do not need to powderize your bulk sample. Instead you could use
a plane and parallel plate. It must be large enough to hold in the instrument
within the area of illumination. However, realize that crystallographic texture
(preferential orientation of atomic planes) will alter relative peak heights, but
not their peak location (2theta or d).
kind regards,

Subject: Sample preparation for XRD analysis
Hello everyone,
I come to the forum to ask a question about sample preparation for Xray diffraction analysis. I have never had this analysis performed before. I have several solid metal samples (mainly Zinc/Aluminum) that I need to prepare in powder form for XRD. Does anyone have information or a contact that offers a sample preparation service?
