2023 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.
Release 2023 of the Powder Diffraction File™ (PDF®) contains 1,143,236 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.
