NbB11
metal· JVASP-125133· NbB11
NbB11 is a niobium boride ceramic compound that combines niobium metal with boron in an 1:11 stoichiometric ratio, placing it within the family of refractory boride ceramics. This material is primarily of research and development interest, studied for extreme-temperature applications where its high melting point and chemical stability are valuable; it represents an emerging class of ultrahigh-temperature ceramics being explored as an alternative to traditional superalloys and established boride phases for hypersonic vehicle components, rocket engine nozzles, and advanced thermal protection systems.
