· SrTaO3

Strontium tantalate (SrTaO3) is a perovskite ceramic compound combining strontium, tantalum, and oxygen in a structured crystalline lattice. This material is primarily studied in research and emerging applications due to its high refractive index, dielectric properties, and chemical stability, making it of interest for photonic devices, optical coatings, and advanced capacitor applications where traditional oxides fall short. It represents a less-common member of the perovskite family and remains largely in development phases rather than established high-volume production, though its tantalate backbone suggests potential in high-temperature and corrosion-resistant environments.

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.
