With crystalline substances, the pattern creates three-dimensional shavings of diffraction in response to x-ray wavelengths, like the spacing of planes in a crystal lattice. This results in a pattern of lower and higher intensities due to constructive and destructive interferences according to Braggs law.

When monochromatic x-rays scatter from a substance with a structure on this scale, it causes interferences. X-rays are a form of electromagnetic radiation include wavelengths measurable in nanometres (a nanometre is equivalent to one billionth of a metre). View XRD products from Scimed How does XRD work? The degree to which it occurs depends on the relative size of a wavelength compared to the dimensions of the obstacle or aperture it encounters. The technique is often known as x-ray powder diffraction because the material being analysed typically is a finely ground down to a uniform state.Дiffraction is when light bends slightly as it passes around the edge of an object or encounters an obstacle or aperture.

It is non-destructive, and works most effectively with materials that are wholly, or part, crystalline. X-ray diffraction, or XRD, is a technique for analysing the atomic or molecular structure of materials.
