· JVASP-57488· K2Li4UO6

K2Li4UO6 is a lithium uranium oxide ceramic compound belonging to the family of mixed-metal oxide ceramics. This material is primarily of research and development interest rather than established industrial production, with potential applications in nuclear fuel cycles, solid-state ion conductors, and advanced ceramic matrices where uranium-bearing phases are intentionally incorporated. The combination of lithium and uranium oxides makes this compound notable for investigating ionic transport properties and thermal stability in specialized nuclear or energy storage applications where conventional ceramics are insufficient.
