Hello dear researchers,
I have some XRD curves for some amorphous glasses system to confirm their glassy nature and I want use them in calculation of any physical parameters.
Dear prof. Essam
It depends on the phase pattern, if the phase completely without any peaks, I think you can't determine any property. However, if you have several peaks attributed to the presence ratio of crystallite in this phase, so you should determine the amount of crystallite in this phase.
Normally at XRD I-2theta curve you do not have any peaks if you studying amorphous specimens. But you can have a diffuse hump that indicates of nanocrystal structure, so this is not really informative case. And if you have any essential peaks in a specimen (but it expect to be amorphous), then this could be other crystalline phases of non-basic material, that can be crystalline while the basic phase is amorphous. Then you should surch which are this phases. Furthermore from the rocking curves you can tell about the crystallinity degree or blockiness.
You can try some Pair Distribution Function (PDF) on your amorphous material. This can provide you some structural in-sights but you need to use Ag/Mo tube to achieve high Q values.
Dear Essam Ahmed Abdel Wahab ,
with respect to evaluation of radial distribution functions and pair distribution functions from x-ray scatter you should have a look at :
