Minerals Arranged by X-Ray Powder Diffraction
See Help on X-Ray 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 materials.
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), mineral name and chemical formulae
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.
Note: 2 theta (Θ) angle calculated from the Bragg Equation, 2 Θ = 2(arcsin(n λ/(2d)) where n=1;
