The three-dimensional space of atoms is arranged in a long-range order, and the smallest unit of repeated arrangement is called the cell, which can be divided into 7 kinds of crystal systems, 14 kinds of lattice, and 230 kinds of space groups according to the arrangement law.

The main indicators of polymer materials include the type of polymer or its crystallinity. Polymers also exhibit different microstructure, which can also affect the mechanical .properties of polymer materials.

X-ray diffraction (XRD) is a means of research to obtain information such as the composition of a material, the structure or form of an internal atom or molecule by analyzing its diffraction pattern through X-ray diffraction.

Crystals, although long admired for their regularity and symmetry, were not studied scientifically until the 17th century. Let's take a look at the early history of crystallography.

An important indicator of XRD is that there is a very good X-ray light source. The so-called good X-ray light source usually refers to high intensity, high parallelism and high purity. This paper will introduce one of the core technologies of neo-Confucianism, CBO optical path.

The method of assisting internal stress without additional energy proposed in this paper provides an economical and convenient new strategy for improving battery reaction dynamics.

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.

The principle of many characterization devices is to make electrons interact with substances that need to be detected, excite secondary electrons, or make atomic level transitions and backtrips, and release characteristic energy.

As the demand for lithium batteries continues to grow, their production and safety standards urgently need to be improved, so high-resolution, high-throughput 3D inspection systems are essential.

XRD can measure bulk and powder samples, and has different requirements for different sample sizes and properties.

Global X-ray diffractometer (XRD) has developed steadily in recent years, and China is a market with great development prospects.
