Calcium carbonate CaCO3 is a rich mineral resource in the earth's crust. It belongs to ABO3 crystal and is a very important inorganic filler widely used in papermaking, food, medicine and other industries.

X-ray diffraction (XRD) is a commonly used method to determine the crystalline structure of the substance and conduct qualitative analysis of the substance. Through the X-ray diffraction of the material, the diffraction pattern is analyzed for the phase analysis of the compound and the determination of the crystal structure, and the information of composition, structure or morphology is obtained.

The samples were tested in the laboratory after sample preparation according to the requirements of XRD powder preparation. The collected atlas was qualitatively analyzed, the phase composition was determined by matching retrieval, and the crystal structure data file of the phase was found.

XRD qualitative detection is convenient, faster and less interference than traditional detection methods. With the continuous innovation of technical means, X-ray diffraction technology will have a broader application prospect in the field of material analysis.
