China Benchtop Xrd Applications Are Widely Used

What is the use of the China benchtop xrd, can you see its purity? Or can you see that it contains a certain functional group?

X-rays illuminate the material and cause scattering. The coherent scattering of X-rays by crystalline substances is a phenomenon of diffraction, that is, the phenomenon that the beam is not diverged but the direction is changed while the incident beam is emitted, and its wavelength remains unchanged. This is a phenomenon unique to crystalline substances.

Most solid materials are crystalline or microcrystalline or quasi-crystalline, and all produce X-ray diffraction. The crystal microstructure is characterized by a periodic long-range ordered structure. The X-ray diffraction pattern of a crystal is a physical transformation of a stereoscopic scene of a crystal microstructure, containing all the information about the crystal structure. The X-ray diffraction pattern can be obtained with a small amount of solid powder or a small sample.

The Chinese benchtop xrd (X-ray diffraction detector) is currently the most powerful method for studying the crystal structure (such as the type and position distribution of atoms or ions and their groups, the shape and size of the unit cell, etc.). Chinese benchtop xrd is especially suitable for phase analysis of crystalline materials. The crystalline material constituent elements or groups are different or have different structures, and their diffraction patterns show differences in the number of diffraction peaks, the angular position, the relative intensity order, and the shape of the diffraction peak.

Therefore, the qualitative analysis of the phase composition and structure of the sample can be completed by comparing the X-ray diffraction pattern of the sample with the X-ray diffraction spectrum of the known crystalline substance; by analyzing and calculating the diffraction intensity data of the sample, it can be completed. Quantitative analysis of the phase composition of the sample; Chinese benchtop xrd can also determine the size of the grain in the material or its orientation (texture of the material), etc., and the application surface is very common and extensive.

At present, China’s desktop xrd is mainly used for inorganic substances, and it is less used for organic substances.
