· Y1 Sc1 Be1

Y1Sc1Be1 is an experimental ternary intermetallic compound combining yttrium, scandium, and beryllium—a research-phase material exploring lightweight, high-temperature structural possibilities in the rare-earth and beryllium family. This composition belongs to the broader class of rare-earth beryllides, which are investigated primarily in academic and advanced materials research rather than established industrial production. The material would be of interest to engineers exploring extreme-environment applications where density reduction and thermal stability are critical, though it remains in the development stage without established commercial supply chains or extensive property databases.
