· Sr1 Ta2 Bi2 O9

Sr₁Ta₂Bi₂O₉ is an ternary oxide ceramic compound combining strontium, tantalum, and bismuth—a research-phase material belonging to the family of complex perovskite and Aurivillius-phase oxides. This compound is primarily of interest in materials research for photocatalytic and electronic applications rather than established commercial production. Engineers would investigate this material for potential use in photocatalysis under visible light, ferroelectric devices, or other functional ceramic applications where the combination of bismuth (known for band gap tuning) and tantalum (a high-refractive-index, corrosion-resistant element) offers synergistic benefits over conventional binary or simpler ternary oxides.

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.
