X-ray diffraction Software’s and Tools
There are a lot of tools (free and paid) available for visualizing and analyzing X-ray diffraction properties and data. Here is a list of tools available in internet that can download from the corresponding sites.
Commercial Tools (Demo version available)
Match! is an easy-to-use software for phase identification from powder diffraction data, which has become a daily task in material scientists work. Match! compares the powder diffraction pattern of your sample to a database containing reference patterns in order to identify the phases which are present. Single as well as multiple phases can be identified based on both peak data and raw (profile) data. As reference database, you can apply the included free-of-charge COD database and/or ICSD/Retrieve (if you have a valid licence), use any ICDD PDF product, and/or create a user database based on your own diffraction patterns. The user database patterns can be edited manually, imported from peak files, calculated from crystal structure data (e.g. CIF files), or imported from your colleague’s user database. Demonstration Version-If you are interested to use MATCH!, you can download a time-limited demonstration version free-of-charge. Brochure- A product brochure including feature list, system requirements and prices is available for download.
Main features of XPowder are,Automatic and search/match phase identification in combination with the ICDD Powder Diffraction File (PDF2),Display stick, hkl-indices and information for PDF patterns,Boolean searching [(Name (And, And, And) + Chemical (And, Or, Not] + PDF sub-files + deleted patterns),automatic refinement and graphical adjustment of lattice parameters.The determination of amounts of different phases in multi-phase samples is automatically accomplished by LS pattern-fitting in experimental standard patterns and observed X-ray scattering. Intensities are fitted including some fitting parameters, i.e. peak position and absorption correction.

PowderCell –Visualize crystal structures and calculate powder patterns -W. Kraus and G. Nolze
PowderCell is an excellent tool to,
- support the structure determination using powder diffraction data
- facilitate the teaching because of the simulation of experimental influences on powder pattern or the visualisation crystallographic properties (space-group symmetry, special positions, extinction laws, subgroups….)
- support practical problems, e.g. quantitative analysis of mixtures, phase identification, existence of preferred orientations, estimation of grain size and lattice strain etc.
GSAS + EXPGUI -Rietveld refinement of crystal structures from single crystal and powder diffraction-Robert von Dreele, Allen Larson, Brian Toby
GSAS (General Structure Analysis System) is a comprehensive system for the refinement of structural models to both x-ray and neutron diffraction data. The GSAS package can be used with both single-crystal and powder diffraction data (Rietveld analysis), even both simultaneously. Neutron data can be either from single-wavelength instruments, or for those a bit more masochistic, time-of-flight instrumentation. Up to 99 different sets of data can be modeled using mixtures of up to 9 different phases.GSAS has been created by Allen C. Larson and Robert B. Von Dreele of Los Alamos National Laboratory. Executable versions of GSAS are distributed more-or-less freely
Espoir -Ab initio crystal structure determination -Marc Mileur and Armel Le Bail
Espoir is a reverse Monte Carlo and pseudo simulated annealing code for ab initio crystal structure determination, either from “scratch” (from a completely random starting model) or by “molecule location” (analogous to the Molecule Replacement method), fitting either to the structure factors amplitudes “|Fobs|” extracted by powder diffractometry or to single crystal data (not any potential needed). This is a “last chance” program which we recommend to use only after failing with classical methods (Direct and Patterson methods).
PDFgetX2 -Obtain atomic pair distribution function from powder diffraction data-X. Qiu, J. Thompson, S. Billinge
PDFgetX2 is a GUI driven user friendly program to obtain the atomic pair distribution function (PDF) from X-ray powder diffraction data
