Cement is a common building supplies, generally divided into ordinary Portland cement, Portland cement mixed materials and special cement, the use of Portland cement is more.

Recently, Applied Clay Science reported "High-pressure Raman scattering and X-ray diffraction study of kaolinite, Al2Si2O5(OH)4."

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.

This paper mainly analyzes the cause of a black spot phenomenon on the negative surface of lithium iron phosphate battery.

A new study from BESSY II analyzes the formation of skomingons in dysprosium and cobalt ferromagnetic films in real time with high spatial resolution.

In this paper, we briefly analyze one (actually two) crystal defects, one fault and layer fault in these three crystal structures. Other crystal structures also have faults and layer faults.

X-ray technology plays a vital role in medical and scientific research, and recent advances in X-ray technology are enabling brighter, stronger beams and imaging of increasingly complex systems under real-world conditions.

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.

In recent years, with the demand for clean energy and the development of a net zero greenhouse gas emission economy, the field of electrocatalysis has attracted great interest.
