X-ray diffraction uses monochromatic X-ray as diffraction sources and can generally penetrate solids. X-ray diffraction gives the bulk phase structure information of the material.

X-ray diffraction is mainly based on qualitative phase analysis, but it can also be quantitative analysis. The phase composition of the sample can be qualitatively analyzed by comparing the X-ray diffraction spectra of the sample to be measured with those of the standard material. By analyzing and calculating the diffraction intensity data of the sample, the quantitative analysis of the phase composition of the sample can be completed

According to the x-ray diffraction pattern information, the sample can be determined whether amorphous or crystalline. The crystallinity of the sample can be qualitatively known. By comparing with the standard spectrum, it is possible to know which phase the measured sample is composed of.

As an important method of structure study, X-ray diffraction has a very important application in the study of catalytic materials and other materials. X-ray diffraction technology has the advantages of non-destructive, high measurement accuracy, and can obtain a lot of information about crystal integrity.
