XRD records the diffraction or reflection of a beam of X-rays by solids, including geological samples. The unique arrangement of atoms in each mineral’s crystal structure interacts with the X-ray beam, producing regions of diffraction intensity, or peaks, diagnostic for that mineral.

X-ray diffraction machine, Union College Geology Department. and match capabilities using the installed ICDD PDF-2 (1996) powder diffraction file database. An online search of a standard database for X-ray powder diffraction patterns enables quick phase identification for a large variety of crystalline samples [442].

• The PDF card for an entry contains much useful information, including literature references. II. FINDING XRD REFERENCE PATTERNS IN JADE The Powder Diffraction File (PDF) is a database of X-ray powder diffraction patterns maintained by the International Center for Diffraction Data (ICDD). In older literature, you may see reference to JCPDS cards. The JCPDS database was the predecessor to the PDF. The "software" is based on the previous XPowder12 program, which inherits all calculation algorithms and access to databases PXRD (except type "PDF2.DB"). XPowderX can coexist with their predecessors XPowder and XPowder12 on the same computer and share with them databases and sample files. - Phases are identified from XRD patterns by comparing peak positions with database entries - Search/Match software & database are required - Various commercial / open programmes and databases - Qualitative (sometimes semi-quantitative) results are obtained - Phase identification is independent of Rietveld refinement (must be done before) To bring up the database setup dial in Jade, go to the main menu ‘Database | Database Setup …’. Now, all you need to do is to select the current year PDF from the list and click the Start button to let Jade index the new set.
