Diffractiometry is a versatile analytical technique used to characterize the crystalline structure of materials. It relies on the principle of diffraction, where waves of energy, typically X-rays or neutrons, are scattered by the regular arrangement of atoms within a crystal lattice. When these waves interact with the crystal, they interfere constructively and destructively, producing a diffraction pattern. This pattern is unique to the specific crystal structure and the spacing of its atomic planes.

In a diffractiometer, a source generates the incident radiation, which is then directed towards a sample. Detectors measure the intensity of the diffracted radiation at various angles. By analyzing the angles at which diffraction peaks occur and their corresponding intensities, scientists can determine key information about the material. This includes identifying crystalline phases present, determining unit cell dimensions, assessing crystallite size, and characterizing preferred orientation (texture).

The interpretation of diffraction patterns often involves comparing experimental data to known standards or using sophisticated computational methods. Diffractiometry is employed across a wide range of disciplines, including materials science, chemistry, geology, and pharmaceuticals, for quality control, research and development, and failure analysis.
