If your budget does not allow for a full ICDD PDF-4 license, you do not need to turn to illegal downloads. Excellent, completely free, and open-access crystallographic databases exist that integrate with standard XRD analysis tools. 1. Crystallography Open Database (COD)
Data is stored in the standard Crystallographic Information File (.cif) format.
Provides calculated diffraction patterns and electronic properties for hundreds of thousands of compounds. 3. RRUFF Project In reality, The COD is the premier open-access
While the full PDF-4+ 20xx database is paid, ICDD occasionally offers limited versions or trial periods. The most common free tier is the (often available for educational use).
Many XRD instrument manufacturers (e.g., Bruker, PANalytical) bundle ICDD licenses with their hardware.
The ICDD is a non-profit scientific organization that manages copyrighted, peer-reviewed data [1]. If your budget does not allow for a
Every entry undergoes rigorous computerized and human editorial review to ensure maximum accuracy.
