· JVASP-52278· YUO4

YUO4 is an yttrium uranium oxide ceramic compound belonging to the family of actinide-bearing ceramic oxides. This material is primarily of research and nuclear engineering interest, with applications in nuclear fuel development, radiation shielding, and advanced ceramic matrix composites where thermal stability and radiation resistance are critical requirements. Its selection would be driven by specialized nuclear or high-energy applications requiring materials that can withstand extreme irradiation environments where conventional ceramics would degrade.
