Analysis of data
Using sophisticated Rietveld software such as Fullprof or Topas, there can be further analysis of powder diffraction data. A quantitative analysis of all crystalline components can be obtained from the integrated intensities. 
Applications of XRD
They include identification of crystalline particles which cause tiny faults in bulk glass, and measurements of crystalline coatings for texture, crystallite size and crystallinity.

Interesting facts
Powder x-ray diffraction (XRD) uses x-rays to investigate and quantify the crystalline nature of materials by measuring the diffraction of x-rays from the planes of atoms within the material. 
Nobel prizes for research with X-Rays
Computer programs exist to do this quickly and efficiently, and can reveal information about the sample including d-spacing, elements that are present and crystalline phases.

Powder diffraction
Now that the effect of diffraction on a crysalline sample has been described, it is time to discuss the core concept of this module: how diffraction of a polycrystalline sample (usually a powder) works.
