Pulverdiffraks

Pulverdiffraks, a term derived from the Swedish words "pulver" (powder) and "diffraktion" (diffraction), refers to the phenomenon of wave diffraction occurring when waves interact with a powdered sample. Typically, this involves X-rays, although other forms of electromagnetic radiation or even particles can exhibit this behavior. When a beam of X-rays strikes a crystalline powder, each tiny crystal within the powder acts as a scattering center. Due to the random orientation of these crystallites, the scattered X-rays will interfere constructively in specific directions, forming a pattern of concentric rings on a detector. This pattern is known as a powder diffraction pattern.

The analysis of a powder diffraction pattern provides valuable information about the crystalline structure of the material. By measuring the angles at which these diffraction rings occur and their intensities, scientists can deduce the size and shape of the unit cell, the arrangement of atoms within the crystal lattice, and identify the specific crystalline phases present. This technique is widely used in materials science, chemistry, mineralogy, and pharmaceuticals for characterization, quality control, and research purposes. It is a non-destructive method that requires only a small amount of sample, making it a versatile tool for understanding the solid-state properties of materials.
