X-ray diffraction technique is widely used in drug analysis. X-ray diffraction technique is an analytical method used to study the structure of a substance. This technique has many applications in drug analysis.

Powder X-ray diffraction, as one of the methods for the study of drug polymorphism, has the advantages of no sample destruction and simple operation.

In the past 10 years, the Institute of Physics of the Chinese Academy of Sciences has used powder diffraction method to determine the crystal structure of many inorganic and organic compounds.

As one of the important means of material structure characterization, XRD is widely used in materials, physics, chemistry, medicine and other fields.

X-ray diffractometer is a device that uses the principle of interaction between X-rays and substances to obtain information such as crystal structure and lattice constant of substances by measuring the diffraction Angle and intensity of X-rays in substances.

Characterization methods of copper monatomic catalysts are often used to determine their structure and properties, and the following are several common characterization methods.

X-ray diffraction technology is widely used in the research of lithium-ion batteries. XRD is a conventional method for qualitative and quantitative analysis of phases in materials.
