XDecomposer: AI Framework for Multiphase X-ray Diffraction Analysis
A new framework called XDecomposer has been developed by researchers for the analysis of multiphase powder X-ray diffraction (PXRD) patterns. This innovative approach does not rely on candidate phase lists, structural templates, or any prior knowledge regarding the number of phases involved. Instead, it frames the analysis of multiphase diffraction as a set prediction challenge, allowing for the inference of an unordered collection of phase-resolved components, their respective mixture proportions, and structural representations within a single architecture. This advancement tackles a significant challenge in structure identification, as real-world synthesis often results in intricate mixtures that existing methods, which typically assume single-phase inputs, struggle to resolve. The findings are available in a paper on arXiv (2605.05866).
