The Powder Diffraction File (PDF) is the only crystallographic database that is specifically designed for material identification and characterization. It is an analysis system that is comprised of crystallographic and diffraction data. These data with embedded data mining and analysis software have been through a quality and classification editorial review system. Release 2015 of the PDF contains 815,000+ unique material data sets. Each data set contains diffraction, crystallographic and bibliographic data, as well as experimental, instrument and sampling conditions, and select physical properties in a common standardized format. The PDF databases are designed to solve your material problems. The PDF is produced in several different formats in order to serve different groups of users.

PDF-2 is a collaborative product between ICDD, FIZ, and NIST. It is designed for inorganic materials analyses. Many common organic materials from ICDD are added to this database to facilitate rapid material identification.

PDF-4+ is our most advanced database, designed for both phase identification and quantitative analysis. This database has comprehensive material coverage for inorganic materials and it contains numerous additional features such as digitized patterns, molecular graphics, and atomic parameters. Features to enhance the ability to do quantitative analysis have been incorporated into PDF-4+.

WebPDF-4+ provides the needed portability for accessing the PDF-4+ database via the internet. It enables full functionality of the PDF-4+ database using a high-speed internet connection. WebPDF-4+ is delivered as a USB compatible dongle.

PDF-4/Minerals is the most comprehensive collection of mineral data in the world! Ninety-seven percent of all known mineral types, as defined by the International Mineralogical Association (IMA), are represented in the database, as well as many unclassified minerals. PDF-4/Minerals is a subset of the PDF-4+ database, which includes all of the software features incorporated into PDF-4+.

PDF-4/Organics is a highly targeted database with the world’s largest collection of pharmaceutical excipients and polymer materials. It is designed for a multitude of applications in pharmaceutical, regulatory, specialty chemical, biomaterial, and forensic fields. The product has all of the display software and data mining capabilities contained in the PDF-4 family of products.

Printed Books and Indexes include ICDD's experimentally collected diffraction patterns and search manuals. These materials have been produced annually for 65 years, and are commonly used as reference books.
