Sodium uranate (Na₂UO₄) is an inorganic ceramic compound containing uranium in the hexavalent oxidation state, belonging to the family of uranate materials studied for nuclear fuel and waste management applications. This material is primarily of research and industrial interest in nuclear engineering, where it serves as an intermediate compound in uranium processing, fuel fabrication, and radioactive waste immobilization; it is notably used in the production of enriched uranium fuels and as a constituent phase in ceramic waste forms designed to incorporate and safely contain uranium isotopes.
