X-Ray Diffraction X-ray powder diffraction (XRD) is a rapid analytical technique primarily used for phase identification of a crystalline material and can provide information on unit cell dimensions. The analyzed material is finely ground‚ homogenized‚ and average bulk composition is determined. Fundamental Principles of X-ray Diffraction Max von Laue‚ in 1912‚ discovered that crystalline substances act as three-dimensional diffraction gratings for X-ray wavelengths similar to the spacing of
