ceramic

· JVASP-41154· Na2TlBi

Na2TlBi is an intermetallic ceramic compound composed of sodium, thallium, and bismuth, belonging to the family of ternary metal oxides or intermetallic phases with potential semiconductor or thermoelectric properties. This is primarily a research material rather than an established industrial ceramic, studied for its electronic structure and potential applications in solid-state devices where the combination of heavy elements (Tl, Bi) may enable interesting transport properties. Interest in this compound class stems from the thermoelectric potential of bismuth-based materials and the unique electronic contributions of thallium in ceramic matrices.
