JCPDS (Joint Committee on Powder Diffraction Standards)

The JCPDS, or Joint Committee on Powder Diffraction Standards, is an organization that creates and maintains a comprehensive database of known diffraction patterns for various materials in powdered form. These patterns are generated through X-ray diffraction, a technique that identifies the atomic structure of materials. Researchers and scientists use the JCPDS database to compare experimental diffraction data with known patterns, helping them accurately identify and analyze the composition and structure of materials in fields like chemistry, physics, and materials science. Essentially, it serves as a reliable reference guide for material identification using X-ray diffraction data.
