Be2NbSb
metal· JVASP-74807· Be2NbSb
Be2NbSb is an intermetallic compound combining beryllium, niobium, and antimony—a research-phase material exploring the property space of lightweight refractory intermetallics. This compound belongs to the family of high-melting-point metals and intermetallics being investigated for extreme-environment structural applications where conventional alloys reach their thermal or weight limits. While not yet in widespread production use, materials in this beryllium-niobium system are of interest to aerospace and defense researchers seeking damage-tolerant alternatives to ceramic matrix composites or nickel superalloys in specialized high-temperature, weight-critical components.
