· JVASP-37481· Yb3Ta

Yb3Ta is an intermetallic ceramic compound combining ytterbium and tantalum, belonging to the rare-earth transition-metal ceramic family. This material is primarily of research and development interest for high-temperature structural applications, particularly in aerospace and materials science contexts where extreme thermal stability and potential oxidation resistance are investigated. Its notable density and rare-earth composition position it as a candidate for advanced refractory or functional ceramic applications where conventional superalloys or oxides may be limited.
