Hello,
I have differents JCPDS cards number and i want to find the corresponding PDF (Powder Diffraction File) and/or COD ID (Crystallography Open Database), is there any website that list all JCPDS files to extract the chemical composition or the structure ?
JCPDS (now ICDD) is commercial database, so you either purchase it or contact a researcher having licensed access. COD is fully free, you may search cif files on their website. The cif files have full information about the material.
Suraj Madake is correct - ICDD is the modern name for the JCPDS. I am not sure if this is what you are asking, but if you have an old JCPDS file number (xx-xxxx), the equivalent PDF-4 number probably is the same but with a "00-" prefix (00-xx-xxxx), which indicates it is from the ICDD powder file.
Note if you have a license for ICDD's PDF-4 database, you can use the Sieve+ tool to run a search on chemistry to find all the matches.
The COD database is smaller, but free, and you can easily run chemistry searches using their web interface at
Also note that the COD provides a downloadable databases which are directly readable using EVA (Broker) and HighScore (Malvern PANalytical) software for search-match, etc.
