ICDD PDF database

The ICDD PDF database, maintained by the International Centre for Diffraction Data, is a comprehensive collection of powder diffraction patterns used to identify and analyze crystalline materials. It contains thousands of entries, each representing a unique material's diffraction data, which scientists use to determine the structure, composition, and properties of substances like minerals, metals, and pharmaceuticals. Researchers access this database to match their experimental results against known patterns, aiding in material identification and quality control across various fields, including chemistry, materials science, and geology.
