An X-Ray Diffraction (XRD) job typically involves analyzing materials using X-ray diffraction techniques to determine their crystallographic structure, phase composition, and other properties. Professionals in this role operate XRD instruments, prepare samples, interpret diffraction patterns, and generate reports. These jobs are common in research labs, materials science, geology, pharmaceuticals, and quality control for industries that work with crystalline materials. Strong analytical skills and knowledge of X-ray physics, crystallography, and data analysis software are often required.
