BaNpO₄ is a barium neptunium phosphate ceramic compound that belongs to the family of actinide-bearing phosphate ceramics. This material is primarily of research and nuclear waste management interest rather than conventional engineering use, as it represents a potential immobilization matrix for neptunium-237 and other actinides in deep geological repositories. The phosphate ceramic family offers high chemical durability and resistance to aqueous leaching, making such compounds candidates for long-term containment of radioactive species in safeguard and disposal applications.
