: An open-access database specifically tailored for powder diffraction that can be used with free software like QualX2.
Modern XRD software (like HighScore Plus or EVA) requires valid license keys to communicate with the PDF database.
Since the PDF-4 database is expensive, many researchers use free, open-access crystallographic databases for phase identification:
Files labeled as software cracks frequently contain hidden trojans, spyware, or ransomware. Clicking a fake download link can encrypt your university or corporate computer network, leading to catastrophic data loss and costly ransoms. 2.

The PDF-4 (Powder Diffraction File) is the flagship product of the International Centre for Diffraction Data (ICDD), a non-profit scientific organization founded in 1941. It is a comprehensive crystallographic database used primarily for identifying crystalline materials, a common task in fields like materials science, chemistry, geology, and pharmaceuticals. The PDF-4 is designed to support both rapid phase identification and quantitative analysis. It combines powder and single-crystal data into a single, powerful searchable database, offering features like digitized patterns, molecular graphics, and atomic coordinates to enhance quantitative analysis.
The PDF-4 family includes several targeted versions, each designed for specific research needs:
If you do not have a license and need open-access diffraction data, the scientific community often uses these alternatives: Crystallography Open Database (COD) Clicking a fake download link can encrypt your
If you are looking for information on specific structural data, I can help you search the Crystallography Open Database (COD) for free, or point you to the official ICDD licensing page to get a quote for the PDF-4+ database.
The from the International Centre for Diffraction Data (ICDD) is the gold standard for identifying crystalline materials via X-ray diffraction (XRD). It contains:
