Si2Tb

Si₂Tb is a rare-earth silicide ceramic compound combining silicon with terbium, belonging to the family of transition metal silicides used in high-temperature structural applications. This material is primarily of research interest for advanced thermal and refractory applications where exceptional high-temperature stability and oxidation resistance are required. The rare-earth silicide family shows promise in aerospace and nuclear contexts, though Si₂Tb remains an uncommon engineering choice compared to established alternatives like MoSi₂ or standard silicon carbide ceramics.
