· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
