· JVASP-29245· USeO5

USeO₅ is an inorganic ceramic compound containing uranium, selenium, and oxygen—a mixed-metal oxide belonging to the family of complex uranium selenates. This is a specialized research material rather than a commercial engineering ceramic; its development is primarily driven by nuclear fuel chemistry, materials science, and fundamental studies of actinide compound behavior under extreme conditions. The material is notable for its potential applications in nuclear waste management, fuel chemistry research, and understanding uranium compound stability, where selenium incorporation may offer insights into corrosion resistance or phase stability relevant to long-term storage scenarios.
