ceramic

· JVASP-85497· UH2O4

UH2O4 is a ceramic compound belonging to the uranium oxide or uranium-bearing oxide family, characterized by a dense crystalline structure. This material is primarily of research and specialized industrial interest, with applications in nuclear fuel systems, radiation shielding, and high-temperature refractory components where uranium-based ceramics offer unique thermal stability and neutron absorption properties. Engineers would select this material in contexts requiring extreme temperature performance or specific nuclear material properties, though its use is heavily regulated and restricted to specialized nuclear, defense, and research applications.
