The power conditions depend on the X-ray tube as the target material and focus type. Although Cu targets are widely used for diffraction, the use of Cu targets for residual austenite analysis is not recommended because of the strong fluorescence of iron-based materials.

Asbestos, also known as "asbestos", refers to silicate mineral products with high tensile strength, high flexibility, resistance to chemical and thermal erosion, electrical insulation and spinnability. The three most common types are chrysotile, iron and cyanite.

In the process of drug development, the properties and structure of drug crystal powders play a crucial role in their efficacy and safety, and the application of X-ray diffraction (XRD) technology provides us with a powerful tool.

Three-dimensional covalent organic frameworks, due to their structured nanochannels, open pore environment and good stability, have gained more and more attention

In this paper, a series of hard carbon materials with adjustable structure were prepared using chitosan as carbon source, and the relationship between the evolution of hard carbon structure and the properties of sodium storage was analyzed.

By X-ray diffraction of the material and analysis of its diffraction pattern, information such as the composition of the material, the structure or morphology of the internal atoms or molecules is obtained.

Many materials through rolling, extrusion and other deformation processes, or even if not deformed, the grains in the polycrystal show more or less statistical uneven distribution, this organizational structure is called texture.

The precursor of ternary material is a low-cost compound of variable valence metal, which will be oxidized in the air, and the higher the drying temperature, the more serious the oxidation degree, and the general choice of air atmosphere drying.

As a means of characterizing crystal structure and its change rule, XRD is widely used in many fields such as materials, chemistry, ceramics, metallurgy and minerals.

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.
