X-ray diffraction is a non-destructive-analysis technique for the identification and the qualitative to semi-quantitative determination of the different crystalline phases of the present compositions in a sample that is in the form of powder.
The identification is fulfilled throughout the comparison of an X-ray diffractiongrame, which is obtained from an unidentified sample, to an international database that contains diffractiongrame references for more than 70000 phases.
The modern diffractometers, controlled by a PC, utilize routine-automatic methods for measuring, maintaining and interpreting the produced diffractiongrame, even for the most complicated mixtures.
