· JVASP-25606· NaUBO5

NaUBO5 is a sodium uranium borate ceramic compound, representing a specialized inorganic ceramic material with uranium-bearing chemistry. This material is primarily of research and nuclear materials interest rather than mainstream engineering application, studied for its potential in nuclear waste immobilization, uranium chemistry research, and understanding of borate crystal structures in the uranium oxide family. The combination of sodium, uranium, and borate chemistry makes it notable in specialized nuclear materials science contexts, though practical industrial adoption remains limited compared to conventional structural ceramics.
