About Y3U2O10
Y3U2O10 is a complex oxide composed of yttrium, uranium, and oxygen. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions. Its electronic character is defined as semiconducting, making it an intriguing subject for studies involving electronic transport and oxide-based materials science.
Given its status as a well-documented material with multiple reported structures across major databases, this compound serves as a significant reference point for understanding uranium-yttrium-oxygen chemistry. Its stable nature provides a reliable foundation for researchers investigating the interplay between heavy actinide elements and rare-earth oxides in solid-state systems.
Key Properties
