Phase Identification & Quantitate
PDF-4+ 2018 contains 398,726 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 rapidly searched for unknown phase identification. Extensive data mining is facilitated with 125 display fields coupled with 72 searches.
PDF-4+ is designed to support automated quantitative analyses by providing key reference data required for these analyses. It also contains an array of tools that supplement conventional analyses, such as a full suite of data simulation programs enabling the analysis of neutron, electron, and synchrotron data, in addition to conventional X-ray data.
PDF-4+ features digitized patterns, molecular graphics, and atomic coordinates. These features incorporated into PDF-4+ enhance the ability to do quantitative analysis using third party software by any of three methods: Rietveld Analysis, Reference Intensity Ratio (RIR) Method, or Total Pattern Analysis.
New for 2018: PDF-4+ is now eligible for a combo site license with PDF-4/Organics.
Using PDF-4+ 2018
- Subfile – select filters related to assigned subfiles/subclass.
- Environment – select filters related to the environment (especially temperature and pressure).
- Atomic Coordinates – filters based on entries that contain atomic coordinates or a cross-reference to an entry with atomic coordinates.
- Raw Diffraction Data (PD3) – filters based on entries with high quality raw experimental data that can consist of nano-crystalline materials, semi-crystalline materials, or amorphous materials.
- Status – select filters based on the status of the pattern, which can be Primary, Active, or Deleted.
- Quality Mark (QM) – select filters related to the quality evaluation assigned to the data.
- Database – search the entire database or select the data entry source (i.e., ICDD (00) – ICDD’s experimental patterns).
A Powder Diffraction FileTM (PDF) Card displays all of the scientific and bibliographic data available for a particular PDF entry and is organized into the following categories:
Temperature Series, Toolbox, Property Sheet, 2D Structure, View 3D Structure, Bond Distances/Angles, Simulated Electron Spot Pattern, Electron Backscattering Pattern, Ring Pattern, Simulated Diffraction Profile, Raw Diffraction Data (PD3)*.
- Equipment factors
- Historic stick pattern and simulated pattern
- Tabular view of reported data: PDF, Experimental, Physical, Crystal, Optical, Structure, Classifications, Cross-references, References, Comments

ICDD’s search indexing program, SIeve+ for PDF-4+, is designed to search and identify unknown materials. SIeve+ is integrated into the ICDD databases to allow the use of the extensive data mining interfaces, searches, and sorts available to improve accuracy and precision of the identification process. For example, users can utilize the extensive permutable searches in each database, then define their own search subfile or use any of the “application or expert-defined” subfiles and subclasses to increase the accuracy of their phase identification. In many cases, this provides a unique capability to analyze the most difficult problems.
SIeve+ offers a variety of algorithms and options that allow users to optimize results for particular chemistries and both standard and non-standard diffraction systems. SIeve+ features automatic rotation of the eight strongest lines (Hanawalt) or the eight longest of the strongest lines (Fink) or the eight longest lines (Long8) to look for entries that exhibit the best Goodness of Match (GOM). In the last few years, new algorithms have been added to identify non-crystalline materials and complex multi-phase specimens. Most of the algorithms were developed and optimized for a particular type of analysis and the options provide the user with a wide breadth of analytical capability. SIeve+ can be complementary with most commercial software programs. This complementary nature demonstrates the strength of SIeve+ in the analysis of minor and trace phases where the full filtering capability of the PDF-4 databases can be applied.
