Learn the potential of each – as well as the superpower they become when coupled together! In less than one hour, you will walk away with tips and tools to build your confidence and improve your productivity. You’ll be guided by ICDD and Materials Data’s experts and developers.
High-entropy spinels have emerged as a novel class of ceramic materials with remarkable thermal stability, structural complexity, and tunable functional properties, making them highly attractive for advanced technological applications. In our we explored the synthesis and characterization of multi-cation spinel phases, emphasizing the role of configurational entropy in stabilizing their unique crystalline structures. We investigated the phase formation, crystallographic features, and cation distribution within multicomponent spinel-type oxides using advanced X-ray diffraction (XRD) techniques. A critical aspect of our work was the precise structural identification and phase analysis using X-ray diffraction (XRD), reinforced by comprehensive data matching through the ICDD database. This integrative approach not only enabled reliable indexing of complex patterns but also underscored the utility of crystallographic databases in advancing the understanding of entropy-stabilized ceramics. These findings emphasize the critical role of XRD and the ICDD database in the structural characterization of high-entropy ceramics and their development for advanced technological applications.
