2020 ICDD PDF Products


X-ray Diffraction (XRD) is a technique used for determining the atomic and molecular structure of a crystalline material, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. Powder XRD is used extensively for the identification of phases by measuring the diffraction angles and intensities of these diffracted beams, and comparing the resulting diffraction pattern to a reference database of diffraction data.

With our 2020 release of the Powder Diffraction FileTM (PDF®), you are able to view 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.
