· Sm6 Ta2 O14

Sm₆Ta₂O₁₄ is a rare-earth tantalum oxide ceramic compound combining samarium (a lanthanide) with tantalum in a mixed-valence oxide structure. This material belongs to the family of complex rare-earth tantalates, which are of primary research interest for high-temperature applications and functional ceramics rather than established commercial products. The compound is investigated for potential use in advanced ceramics, thermal barrier coatings, and electronic/photonic devices due to the chemical stability of tantalate compounds and the electronic properties imparted by rare-earth doping, though industrial adoption remains limited and most applications remain in the exploratory or laboratory phase.
