XPowder XPowder In The World: This software has been developed for the analysis of natural minerals, artificial compounds, biological crystals and other solid materials, using techniques of Powder X-Ray Diffraction (PXRD). Main applications are the identification, quantification and characterization of the crystalline components of solid samples. Database access This software can access several databases. • AMSCD free Mineral database. • PDF2.DAT database of the ‘The International Centre for Diffraction Data (ICDD)’ • P2D2 (Predicted Powder Diffraction Database).The P2D2 free database currently includes twelve text files, each one with approximately 100000 framework structure compounds, which can be automatically indexed by XPowder, individually or combined for search-match analysis. • Custom databases directly created by the user or imported from other databases ('My database').

Rigaku instrumentation covers: X-ray diffraction (XRD), X-ray spectrometry (XRF), SAXS, protein and small molecule X-ray crystallography, Raman, X-ray optics. The analysis per se is done following six major steps: (1) peak profile fittings using preset common profile functions or user-defined profile functions (2) organization of X-ray diffraction lines under different groups (phases) if a pattern is one of a multi-phase sample (3) assignment of Miller indices to the fitted lines (4).

Databases are not included in XPowder setup programs and they have to be acquired by user.

• Plots:, and. Qualitative • phase identification using the ICDD Powder Diffraction File ( PDF2), AMCSD, P2D2 and Customized databases. • Display stick, hkl-index and information for database patterns. • Boolean searching [(Name (And, And, And) + (And, Or, Not] + subfiles + pdf2 deleted patterns) or AMCSD code. Two methods can be optionally used: • LS pattern experimental patterns. Intensities and some parameters ( i.e.

Peak position and absorption correction) are fitted. XPowderX applies Normalized Methods using RIR ( Reference Intensity Ratio) database values or customized PIR ( Pattern Reference Intensity) measured values. • The relative mixtures of from are used to simulate that of the problem sample using minimal squares methods.

Scale factor is calculated using Normalized PIR Methods. Intensities are corrected by some fitting parameters, i.e. Single Peak Displacements, 2 θ Zero-Shift, Profile Broadening and Absorption. Result includes Components, Computed patterns, Difference diffractogram and compositional table.

In both methods According R-Factor and Standard deviations are computed. Profile Analysis Pseudo-Voigt, Gaussian, Cauchy and Pearson VII asymmetric models. Instrumental corrections.
