Phase identification of a coarse-grained trace component in a mineral powder using 2D XRD

AppNote XRD1103: Phase identification of a coarse-grained trace component in a mineral powder using 2D XRD

 

Grain sizes dramatically influence observed 2D XRD images, with fine grains appearing as rings and coarse grains as spots. In the classical approach, XRD software only attempted crystal phase identification after converting the 2D diffraction image to a 1D profile. Information about grain conditions in the 2D diffraction image was not used. The Powder XRD plugin for SmartLab Studio II uses both the 2D diffraction image and a 1D profile derived from it for analysis. Using information about crystal grains obtained from 2D diffraction images for search/match, phase identification can be done easily.
