· JVASP-91999· USe3

USe3 is a uranium selenide ceramic compound that belongs to the actinide chalcogenide family, representing a specialized material class with potential applications in nuclear fuel cycles and advanced materials research. While not widely deployed in mainstream engineering, uranium selenides are investigated for their thermal, electrical, and structural properties in high-temperature nuclear contexts and as model systems for understanding actinide chemistry. Engineers would consider this material primarily in advanced nuclear fuel development, materials research for extreme environments, or specialized applications where uranium-bearing ceramics offer unique combinations of properties unavailable in conventional ceramics.
