The degree of relative crystallinity of the bio-composites was determined using XRD method. Two distinguishable crystalline peaks were observed in the 2[phonetic_theta] range of 5 to 40 掳 which indexed as 020 and 110 respectively. It was noted that the maximum peak of intensity at 020 ...

The per cent crystallinity of FAZ-A samples has been ascertained by comparing the ratio of intensity of the peak at 560 and 480 cm–1 with the corresponding ratio for a standard sample. The per cent crystallinity of FAZ-A is calculated using standard procedure. Results of crystallinity ...

The vast majority of XRD studies report the scattered intensity in arbitrary units. This is adequate for determining crystal structures, which can be inferred solely from the positions and relative intensities of the diffraction peaks. On the other hand, a key consideration for an XRD imaging syste...

Hence it only shows a broad diffraction peak.If we get something that does not repeat, we get a huge amount of micro diffraction peaks that are going to make this big hump in the spectra. That is an amorphous halo. Most of the time you are going to get partial crystallinity if you ...
