![]() Phase identification – comparing the measured diffraction peaks to a database of known patterns, allowing the identification of the phase(s) within a single sample.Within Newcastle University, we utilise PXRD for applications including: PXRD can be used to characterise a wide range of solid-state materials, including alloys, cements, refractories, pharmaceuticals, nanomaterials and glasses, to name a few. Powder X-ray Diffraction (PXRD) is a powerful rapid analytical technique for the study of single and multi-phase polycrystalline materials. If you are interested in working with us, please get in touch to discuss any potential contract work, or for one-off measurements. PXRD can provide a comprehensive picture of the solid state properties of any crystalline material. In addition to standard experiments, our PXRD facility has the capability to run samples under inert atmosphere (for air-sensitive samples) and under different gases and vapours to monitor the stability of materials under different conditions. Phase quantification using simple profile fitting, LeBail, Pawley or Rietveld refinements.Calculation of unit cell dimensions through pattern indexing.Measurement of crystallite/crystal domain size within discrete crystalline phases (always best to compare with microscopy techniques such as SEM).Through interpretation of diffraction patterns, PXRD analysis allows: Through identification of each pattern within the diffractogram, individual materials (or phases) can be identified and quantified. If more than one material (or phase) is present, then the diffraction patterns for each material is overlapped. When a crystalline sample is exposed to an X-ray beam of known wavelength, a unique diffraction pattern is generated. ![]() those which have a degree of order to their structure. ![]() PXRD is a rapid, non-destructive analytical technique used for the characterisation of crystalline materials, i.e. ![]()
