ceramic

· JVASP-12549· BaTa2Bi2O9

BaTa₂Bi₂O₉ is a complex oxide ceramic compound containing barium, tantalum, and bismuth—a material class typically explored for electronic and photonic applications due to the unique properties imparted by high-density metal oxides. While not a commodity material, this compound belongs to the family of ternary and quaternary oxides investigated for potential use in specialized ceramics, with tantalum and bismuth oxides known for their roles in capacitors, photocatalysts, and radiation-shielding applications. Research on such barium tantalate bismuth systems focuses on tailoring dielectric, optical, or catalytic properties for next-generation electronics and advanced functional ceramics.
