Comprehensive Overview of X-Ray Diffraction: Principles, Techniques, and Applications in Material Science

This paper provides an overview of XRD, including its principles, instrumentation, data analysis, and applications. While visual characteristics can aid in identifying certain minerals, powder XRD remains the most reliable and accurate method for phase identification and structural analysis. Beyond crystallography, XRD offers valuable insights into the short- and intermediate-range structures of amorphous materials such as glasses, revealing its broader relevance in emerging technologies. It is widely used for analyzing powders, solids, thin films, and nanomaterial. XRD is often combined with techniques like SEM, TEM, PCS, EBSD, SPM, DLS, ND, and SAED to enhance material characterization. The paper covers fundamental principles such as Bragg’s Law and X-ray interaction with crystal lattices, as well as advancements in XRD instrumentation, including X-ray sources, diffractometer, and detectors, reflecting the rapid scientific progress in XRD technology.
