One method involves fitting individual line profiles, finding the area of the crystalline peaks, and the total area of the pattern. The ratio is an estimate of the percent crystallinity.When you have fully crystalline material as an option, you can also account for differences in sca

Hi Lubo, Yes, one way to do this is to add a known mass X of a standard (say alumina) to a known mass Y of the glass + crystal sample, giving a weight ratio f = X/Y of standard to sample. Then use x-ray diffraction to get the weight ratio of the standard to only the crystalline part of the sample
