· JVASP-88455· Ba3SrTa2O9

Ba3SrTa2O9 is a complex oxide ceramic composed of barium, strontium, and tantalum, belonging to the family of perovskite-derived compounds used in high-performance dielectric and electronic applications. This material is primarily investigated for microwave and millimeter-wave dielectric resonator applications, where its high permittivity and low loss characteristics enable compact, stable frequency-control components in telecommunications systems. While not yet widely commercialized as a bulk commodity, Ba3SrTa2O9 represents an active research direction in advanced ceramics for next-generation wireless infrastructure, offering advantages over traditional materials in temperature stability and miniaturization potential.

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.
