ceramic

· JVASP-15239· U2AsN2

U2AsN2 is a ceramic compound in the uranium-arsenide-nitride family, representing an advanced refractory ceramic material system. This material is primarily of research interest for high-temperature and extreme-environment applications where conventional ceramics face performance limitations. Its significance lies in its potential for nuclear fuel forms, advanced refractory coatings, or specialized structural applications in environments requiring both thermal stability and chemical resistance, though industrial deployment remains limited and material characterization is ongoing.
