Powder X-ray diffraction (PXRD) operates under the assumption that the sample is randomly arranged. Therefore, a statistically significant number of each plane of the crystal structure will be in the proper orientation to diffract the X-rays.

2023年8月29日 · In powder X-ray diffraction, the diffraction pattern is obtained from a powder of the material, rather than an individual crystal. Powder diffraction is often easier and more convenient than single crystal diffraction since it does not require individual crystals be made.

Powder X-ray diffraction (PXRD) can be used to determine the crystallinity, unit size, and phase purity of the MOF sample through the obtained pattern. The information about unit cell size and phase purity can be extracted through computational models.

2019年7月23日 · Powder X-ray diffraction (XRD) is a common characterization technique for nanoscale materials. Analysis of a sample by powder XRD provides important information that is complementary to various microscopic and spectroscopic methods, such as phase identification, sample purity, crystallite size, and, in some cases, morphology.

This software has been developed for the analysis of natural minerals, artificial compounds, biological crystals and other solid materials, using techniques of Powder X-Ray Diffraction (PXRD).
