Sr2BeNb
metal· JVASP-71581· Sr2BeNb
Sr2BeNb is an intermetallic compound containing strontium, beryllium, and niobium. This material is primarily of research interest rather than established industrial use, with potential applications in advanced aerospace and high-temperature structural systems where the combination of low density (beryllium) and refractory properties (niobium) could offer benefits. The material family represents exploratory work in ultra-lightweight intermetallics, though practical engineering adoption remains limited due to challenges with beryllium toxicity during processing, niobium cost, and manufacturing complexity.
