PDF-4+ 2021

The PDF-4 2021 database is specifically designed for qualitative and quantitative analysis of inorganic materials, and is the world's most comprehensive database of inorganic substances! All data entries in PDF-4 contain information such as powder diffraction data, single crystal structure, two-dimensional Debye rings, selected area electron diffraction (SAED), electron backscatter (EBSD), etc. It can be seamlessly combined with third-party software such as JADE, EVA, Highscore, PDXL, etc. to achieve enhanced analysis functions such as Rietveld analysis, full spectrum fitting, and quantitative analysis.
