· Na3UO4

Sodium uranate (Na₃UO₄) is an inorganic ceramic compound containing uranium in a stabilized oxide form, belonging to the family of actinide ceramics. This material is primarily of research and specialized industrial interest rather than widespread commercial use, with applications concentrated in nuclear fuel chemistry, uranium processing, and advanced ceramics development. Engineers would consider Na₃UO₄ for its chemical stability in uranium metallurgy processes and as a precursor material in nuclear fuel fabrication, though it remains niche compared to conventional uranium dioxide (UO₂) used in reactor fuel.
