BaTa2Bi2O9
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.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
