WebA phase is a crystalline solid with a regular 3-dimensional arrangement of the atoms. The measured diffraction peak positions and intensities are like a fingerprint of a particular crystalline phase. Identification is accomplished by comparison of the measured pattern with the entries in reference databases using a search-match algorithm.
