PDF-4+

What is PDF-4+?

Pdf-4+ contains 412,083 entries. It combines the world's largest sources of inorganic diffraction data from crystals and powders into a single database. The result is a comprehensive collection of inorganic materials, produced in a standardized format that can be quickly researched for unknown phase identification. Extensive data mining is facilitated with 126 display fields coupled to 74 searches.

PDF-4+ is designed to support automated quantitative analysis, providing the key reference data needed for these analyses. It also contains a number of tools that complement conventional analyses, such as a complete set of data simulation programs that allow the analysis of neutron, electron and synchrotron data, as well as conventional X-ray data.

PDF-4+ features digitized patterns, molecular graphics, and atomic coordinates. These features built into PDF-4+ enhance the ability to perform quantitative analysis using third-party software through three methods: Rietveld Analysis, Reference Intensity Index Method (RIR), or Total Pattern Analysis.
