Computerized “cards" can contain much more crystallographic information. Evolution X-Ray Analytical Methods. X-rays were discovered by W.C. Roentgen in 1895, and led to three major uses: • X-ray radiography is used for creating images of light-opaque materials. It relies on the relationship between density of materials and absorption of x-rays. Applications include a variety of medical and industrial Powder Diffraction Methods. ?

Peak Shape Analysis. 19 Jul 2004 The experiment consists of analysing two x-ray films exposed in a powder diffraction camera. In the powder (Debye-Scherrer) method, the x-rays fall on a mass of tiny crystals in all orientations, and the diffracted beams of each order h, k, i form a cone. Arcs of the cones are intercepted by a film surrounding Comment. Cover illustration, created by Peter Zavalij, follows the content of the book. The illustration is inspired by Salvador.

An instrument dedicated to performing such powder measurements is called a powder diffractometer. Powder diffraction stands in contrast to single crystal Diffractometer. ? A scintillation counter may be used as detector instead of film to yield exact intensity data. ? Using automated goniometers step by step scattered intensity may be measured and stored digitally. ? The digitised intensity may be very detailed discussed by programs. ? More powerful methods may be used to Dinnebier 0; InternationalTables 0; Will 0; Young 0; Pecharsky 0.

Phase analysis with the PDF database software for accessing and searching databases. Phase identification was introduced early in the history of powder methods, with the classic paper by Hanawalt, Rinn and Frevel (1938) which contains powder data for 1000 substances. This was the forerunner of the Powder. Diffraction File (PDF), which is now administered PANalytical X'Pert Pro Multipurpose Powder Diffractometer. – Rigaku High-Power P$
