X-ray Diffraction (XRD)
X-ray Diffraction (XRD) is a non-destructive analytical technique used to determine crystalline structure, phase composition, lattice spacing, crystallite size, and degree of crystallinity in materials. When a material is exposed to X-rays, its crystal lattice diffracts the beams in characteristic patterns that serve as a unique structural fingerprint.
At Materials Metric, XRD is applied to identify phases, assess crystallinity, and understand structureโproperty relationships across metals, ceramics, polymers, pharmaceuticals, battery materials, and advanced composites. Our diffraction workflows deliver reproducible peak profiles and defensible structural data supporting materials development, quality control, failure analysis, and regulatory documentation.
Use of XRD
Researchers and manufacturers use XRD to:
โข Identify and quantify crystalline phases
โข Measure crystallinity in semi-crystalline polymers
โข Detect polymorphs or phase transitions
โข Evaluate stress, strain, and lattice abnormalities
โข Determine crystallite size using Scherrer analysis
โข Characterize thin-film orientation and texture
โข Analyze battery electrode structures
Applications of XRD
โข Metals & Alloys: grain orientation, phase fractions
โข Ceramics & Glass: structural verification, purity
โข Polymers: crystallinity, polymer phase transitions
โข Battery Materials: cathode/anode phase characterization
โข Pharma: polymorph identification and stability studies
โข Thin Films & Coatings: texture, orientation, and crystallinity
