X-ray Diffraction Analysis Laboratory
About the Laboratory
X-Ray Diffraction (XRD) is a non-destructive analytical technique used to obtain information about the structures/phases of crystalline materials. It has been widely applied in chemistry, nanomaterial, geology, pharmaceutical industry, glass industry, microelectronics industry, and many other fields. Depending on sample forms, there are two types of diffractometers: single crystal XRD and powder XRD. Single crystal XRD determines the molecular structure at atomic level and therefore provides information such as bond lengths, bond angles, coordination, disorder, etc. Powder XRD is primarily used to identify phases of solid state materials and has found its applications in studying, for examples:
- Phase transitions
- Sample purity
- Lattice parameters
- Crystal size and strain
