Nb5Si3N
metal· JVASP-116604· Nb5Si3N
Nb5Si3N is a niobium silicide nitride compound belonging to the refractory transition-metal ceramics family, designed for ultra-high-temperature structural applications. This material is primarily investigated in aerospace and energy sectors as a candidate for next-generation turbine components, thermal barriers, and oxidation-resistant coatings where conventional superalloys approach their performance limits. Niobium silicides offer superior thermal stability and oxidation resistance compared to traditional nickel-based systems, making them attractive for hypersonic vehicles and advanced power generation, though development remains largely in research and prototype stages.
