Dear Tiza,

please have a look at the links:

https://en.wikipedia.org/wiki/Energy-dispersive_X-ray_spectroscopy

and

https://en.wikipedia.org/wiki/Powder_diffraction

as well as

https://en.wikipedia.org/wiki/X-ray_crystallography

In short:

EDX (energy dispersive x-ray spectroscopy) delivers elemental composition of a sample whereas XRD (x-ray diffraction) is used for determination of the crystal lattice type and its parameters.

Thanks a lot sir.Very useful.
