JCGS (Joint Committee on Powder Diffraction Standards)

The Joint Committee on Powder Diffraction Standards (JCPDS), now part of the International Centre for Diffraction Data (ICDD), is an organization that provides verified reference data for interpreting X-ray diffraction patterns of powdered materials. These patterns act like unique fingerprints for different substances, helping scientists identify and analyze minerals, metals, and other materials accurately. The JCPDS/ICDD databases compile standardized diffraction data, ensuring reliable comparison and identification in research and industry, facilitating advancements in materials science and quality control.
