Pordiffrakcióval, or powder diffraction, is a scientific technique used to analyze the crystalline structure of powdered materials. It involves directing a beam of X-rays or neutrons at a finely ground sample. When the incident radiation interacts with the regularly spaced atoms in a crystal lattice, it diffracts in specific directions, creating a unique diffraction pattern. This pattern is essentially a fingerprint of the material's atomic arrangement.

The principle behind powder diffraction is Bragg's Law, which relates the wavelength of the incident radiation, the distance between atomic planes in the crystal, and the angle at which constructive interference occurs. By measuring the angles and intensities of the diffracted beams, scientists can deduce the spacing of atomic planes, the size and shape of unit cells, and the overall crystal structure.

Powder diffraction is a versatile tool with numerous applications. It is widely used in materials science to identify unknown crystalline phases, determine the purity of samples, and quantify the proportions of different crystalline components in a mixture. In geology, it helps identify minerals. In the pharmaceutical industry, it's crucial for characterizing the solid-state forms of drugs, which can significantly impact their stability and bioavailability. The technique is also employed in chemistry, physics, and even forensics for material characterization. The simplicity of sample preparation and the wealth of information obtainable make powder diffraction an indispensable method in many scientific disciplines.
