In order to calculate the crystallinity of a polycrystalline material (eg. clays), I would like to use XRD. It needs to deconvolute the XRD pattern coming from crystalline part and amorphous part of the material. How can I decompose or deconvolute the XRD graph using PANalytical X pert High score plus, Version 2.0 software.
In order to deconvolute constituent information I suggest the following:
I'm not so sure about HSP V 2.0. But to do determine the amorphous phase if you know all the crystalline phases is by spiking method; add known wt% of crystalline material (not in the specimen candidates), do the quantitative analysis, change the refinement wt% of the crystalline material by its true wt%, in v3 u'll get the amorphous wt%. Or you can do POCNKS : "Quantification of phases with partial or no known crystal structure“ Nicola V.Y. Scarlett and Ian C. Madsen, Powder Diffraction (2006) Vol. 21(4), p. 278 – 284. doi.org/10.1154/1.2362855
