What is Icdd Pdf 4 Database?
Icdd Pdf 4 Database, also known as PDF-4+, is a comprehensive and authoritative database of inorganic and organic materials that contains over 1.1 million entries of digitized patterns, molecular graphics, atomic coordinates, and more. It is produced and maintained by the International Centre for Diffraction Data (ICDD), a non-profit organization that aims to collect, edit, publish, and distribute powder diffraction data for the identification and characterization of materials.
History of Icdd Pdf 4 Database
The history of Icdd Pdf 4 Database can be traced back to the 1930s, when the American Society for Testing Materials (ASTM) started to publish the first powder diffraction data cards. These cards contained information on the crystal structure, chemical composition, and diffraction pattern of various materials, which could be used to identify and analyze them using X-ray or neutron diffraction techniques. In 1941, the ASTM formed a subcommittee to standardize and coordinate the production of these cards, which later became the Joint Committee on Powder Diffraction Standards (JCPDS). In 1978, the JCPDS changed its name to ICDD, and in 1983, it launched the first electronic version of its database, called PDF-1. Since then, the ICDD has continued to expand and improve its database, adding new features and functionalities, such as PDF-2 in 1988, PDF-4/Organics in 2000, PDF-4+ in 2004, PDF-4/Minerals in 2006, and WebPDF-4+ in 2012.
