In X-ray analysis, an instrument used to measure the Angle between an incident X-ray beam and a diffracted X-ray beam. The diffractometer automatically maps the variation of the diffraction intensity with the 2θ Angle.

XRD as a qualitative analysis means is not blind, with the help of analysis software just for convenience, fundamentally speaking, the most important thing is the XRD pattern itself.

The structural stability of SBA-15 is closely related to its pore size and properties, and XRD is one of the effective methods to characterize its structure.

The full name of XRD is X-ray diffraction, which uses the diffraction phenomenon of X-ray in the crystal to obtain the X-ray signal characteristics after diffraction, and gets the diffraction pattern after processing.

To determine whether there is asbestos in talc is usually a combination of polarizing or electron microscopy and X-ray diffraction, and the quantitative analysis of asbestos mainly uses X-ray diffraction method.

Most drugs exist in the form of crystals, using X-ray diffraction, we can obtain the diffraction information of drug characteristics for each different crystal type.

The Guiding Principle of Chiral Innovative drugs clearly stipulates that "the direct method for determination of molecular configuration of chiral drugs is single crystal X-ray structure analysis".

Unlike powder XRD, which is widely used in the late stage of drug development and production, single crystal X-ray diffraction technology plays an important role in the early and middle stages of drug development.

With the gradual increase of drug crystal regulation, the quantitative analysis of the effective crystal in drug preparations is a very important link in the quality control process of drug production.

XRD technology is widely used in the fields of crystallography, physics and metallurgy, including qualitative and quantitative, crystal structure, mechanical analysis, etc. This paper mainly lists its application in polymer research.

The application of XRD in the refractory industry involves all aspects of refractory production. From raw material quality inspection, production process control to product quality inspection.

In drug research and development, crystal research runs through all stages from the screening of lead compounds to the final drug marketing.
