Mohammed M. Obeid

you can determine particle size through XRD by applying Scherrer equation and I recommend you to use expert high score plus software for this purpose..

Good Luck!!

Guillermo R Castro

The main problem with this kind of determination is the symetry of the peak, and the "tales" created by the overlapping with others.
