· Ba2 Sr2 Ta4 O14

Ba₂Sr₂Ta₄O₁₄ is a complex oxide ceramic semiconductor composed of barium, strontium, tantalum, and oxygen in a high-symmetry crystal structure. This material belongs to the family of layered perovskite and tungsten-bronze-type compounds, which are primarily of research interest for their unique electronic and dielectric properties. While not yet established in mainstream industrial production, materials in this compositional family are investigated for potential applications in high-frequency electronics, photocatalysis, and advanced dielectric devices, where the combination of ionic and covalent bonding offers tunable band gaps and ferroelectric or semiconducting behavior.

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.
