ceramic

· JVASP-15173· USO

USO is a uranium-based ceramic compound belonging to the actinide oxide family, characterized by high density and significant stiffness. It is primarily used in nuclear fuel applications, advanced ceramics research, and specialized high-temperature engineering contexts where uranium-containing materials are required for neutron interactions or thermal performance. Engineers typically select USO-based ceramics in nuclear reactor fuel designs and experimental studies of actinide materials behavior, though applications are restricted to regulated nuclear industry contexts.
