Automatic X-ray orientation instrument is an indispensable instrument for precision processing and manufacturing crystal devices. It is widely used in the research, processing and manufacturing of crystal materials.

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.

The composition of the diffraction pattern is mainly the position and intensity of the diffraction peak, and our analysis of the XRD pattern is based on the changes in the intensity and position to explain the changes in the micro and macro of the material.

Micro-ct technology has significant advantages in the characterization of ceramics, which can reveal the composite structure inside the material without damage, and restore the key technology in the production of ceramics.

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

As a new material characterization technology, PDF (Pair Distribution Function) is useful in the study of the local structure of both crystal and amorphous materials.

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.

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.

Dandong Tongda Technology Co., LTD., with professional technology and perfect service, has won the trust of scientific research workers around the world.

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

Micro-xrd can analyze the original state of the sample and carry out phase analysis of various parts of the sample. In this paper, a geological sample lapis Lazuli is taken as an example to further illustrate the effect of micro-diffraction.
