X-ray diffraction is one of the most powerful tools for identifying unknown crystalline phases. And there are various databases that crystallographers can reference against, for instance ICDD. By comparing the positions and intensities of the diffraction peaks against a library of known crystalline materials, the target material can be identified. This action is known as phase search mapping. Because this method of phase search scanning involves the mathematical matching of such scans, it is possible that the phase mathematically matches to the XRD pattern, but not actually be in the sample.

During this webinar, we discuss about such confounding errors where incorrect phases were recognised. And importantly how such errors can be minimized or eliminated by way of narrowing the search mapping by way of understanding the chemistry or elemental composition of the material.
