Xray powder diffraction is one of the most useful analytical tools for material analysis. Whether you are analyzing metals, polymers, semiconductors, geological samples or pharmaceuticals, XRD can provide useful information based upon the powder diffraction pattern.
Among the most common tests are the identification and quantification of the crystalline phases, determination of the percent crystallinity, and analysis of the crystal structure. Other tests that can be performed include residual stress analysis, determining the amount of Retained Austenite in steels and analysis of preferred orientations.
XRD is especially useful for examination of thin films where crystalline perfection, misfit strain and interfacial quality can be determined.
