Application of X-Ray Diffraction Methods for Refractory Raw Material Quality Control

The majority of refractory materials and raw minerals used for their production are crystalline substances. X-ray diffraction techniques can be used successfully for qualitative and quantitative determination of their mineral composition and for analysis of the technologically significant structural features that are most important in a production process. Examples are considered for the main types of refractory materials and are studied with the full-profile Rietveld refinement method in order to reveal control parameters during their production. It is concluded that structural properties of mineral phases should be taken into account that have a considerable effect on refractory material mechanical properties.
