XRD patterns can be used to determine
• Phase Composition of a sample:
– Quantitative Phase Analysis can determine the relative amounts of phases in a mixture by referencing the relative peak intensities
• Unit cell lattice parameters and Bravais lattice symmetry
– Index peak positions
– Lattice parameters can vary and thereby giving the information about, alloying, doping, solid solutions, strains, etc.• Residual Strain (macrostrain)
• Crystal Structure – By Rietveld refinement of the entire diffraction pattern
• Epitaxy/Texture/Orientation
• Crystallite Size and Microstrain
– Indicated by peak broadening
– Other defects (stacking faults, etc.) can be measured by analysis of peak shapes and peak width• The above factors can be also determined as a function of time, temperature, and gas environment in some of the advanced XRD having in-situ heating and controlled atmosphere facilities.
