Syllabus: | Powder diffraction principles, practice and applications - crystallography, specimens, instrumentation, identification analysis and phase analysis. Rietveld analysis. Crystallography basics, including space groups. Diffraction science: single crystal diffraction. Simulation of single crystal intensities: calculating structure factors. Crystal structure data bases (ICSD data base). Instrumental: Specimen requirements and preparation. The Bragg-Brentano diffractometer: optical design/alignment. Operating conditions: choice of generator settings, x-ray tube, slits, detector settings and electronics. Data reduction. Absorption, information depth. Preferred orientation. Extinction. Stacking faults. Identification methods. Search/match analysis with the PowderDiffraction File. Phase Composition Analysis: traditional single-peak and multi-peak methods for thick and thin samples, including the MNI method. Rietveld phase composition analysis. Rietveld Pattern Fitting: Rietveld analysis for crystal structure refinement, cell parameters, phase analysis, texture characterisation, strain analysis, crystallite size analysis. Other methods: Line broadening determination of crystallite size, strain and stacking faults. Texture assessment, crystallinity. Grazing. |
