2019-2020 PDF Product Line

Release 2020 of the Powder Diffraction FileTM (PDF®) contains 1,004,568 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.

The PDF-4+ 2020 database is powered by our integrated search display software. PDF-4+ 2020 boasts 75 search selections coupled with 128 display fields resulting in a nearly limitless choice of data mining options.

The Search Window displays nine tabs. Each tab features multiple search criteria to allow you to data mine the PDF-4+. Searching the PDF-4+ is an iterative process that allows you to input user-defined criteria, view the results, and combine additional criteria to refine your results.

PDF Databases – Why We Are The Best!

More data, higher quality, more content, many types of solid state reference data
  • The world’s largest solid state collections of minerals, metals and alloys, polymers, active pharmaceuticals, and commercial materials
  • The world’s largest and most diverse (by formula) collection of inorganic structures
  • The world’s largest collection of modulated structures
  • Extensive bibliographic collections – thousands of journals, hundreds of thousands of authors
  • Target your identification; get more accurate results using materials classified by chemistry and application by using the PDF’s extensive subfile system
  • Standardized data, nomenclature, and structural classifications plus brand names, trade names, mineral names, zeolite names, and common names of commercial materials

The International Centre for Diffraction Data® (ICDD®) is a non-profit scientific organization dedicated to collecting, editing, publishing, and distributing powder diffraction data for the identification of materials. The membership of the ICDD consists of worldwide representation from academe, government, and industry.
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.
ISO Certified
The only crystallographic database organization in the world with its Quality Management System ISO 9001:2015 certified by DEKRA.
