· JVASP-79043· Lu3Si

Lu3Si is an intermetallic ceramic compound composed of lutetium and silicon, belonging to the rare-earth silicide family. This material is primarily investigated in research contexts for high-temperature applications and advanced material systems, where its combination of rare-earth and refractory properties may offer advantages in extreme thermal or oxidation environments. Lu3Si represents the broader potential of rare-earth silicides as candidates for next-generation aerospace, nuclear, and high-temperature structural applications, though industrial deployment remains limited.
