• Max. sample weight, depending on sample holder: 250 g
• Max. sample height, depending on sample holder: 25 mm
• Max. sample diameter: 70 mm

Applications:

• Phase Composition of a Sample
  • Quantitative Phase Analysis: 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 as a function of, and therefore give you information about, alloying, doping, solid solutions, strains, etc.
• Residual Strain (macrostrain)
• Crystal Structure
  • By Rietveld refinement of the entire diffraction pattern
• Epitaxy/Texture/Orientation
• Variable temperature analysis
• Capillary measurements
• Crystallite Size and Micro strain
  • Indicated by peak broadening.
  • Other defects (stacking faults, etc.) can be measured by analysis of peak shapes and peak width.
Sample: Solid, Thin films and powder
