Minerals Arranged by X-Ray Powder Diffraction

Powder X-ray Diffraction (XRD) is one of the primary techniques used by mineralogists and solid state chemists to examine the physico-chemical

make-up of unknown solids. This data is represented in a collection of single-phase X-ray powder diffraction patterns for the three most intense D

values in the form of tables of interplanar spacings (D), relative intensities (I/Io), hkl plane, mineral name and chemical formuls.

The XRD technique takes a sample of the material and places a powdered sample in a holder, then the sample is illuminated with x-rays of a fixed

wave-length and the intensity of the reflected radiation is recorded using a goniometer. This data is then analyzed for the reflection angle to

calculate the inter-atomic spacing (D value in Angstrom units - 10-8 cm). The intensity(I) is measured to discriminate(using I ratios) the various D

spacings and the results are compared to this table to identify possible matches.

For more information about this technique, see X-Ray Analysis of a Solid or take an internet course at Birkbeck College On-line Courses. Many

thanks to Frederic Biret for these data.
