BaTaO3
ceramic· BaTaO3
Barium tantalate (BaTaO₃) is a dense ceramic compound belonging to the perovskite family, valued for its high dielectric constant and thermal stability. It is primarily used in advanced capacitor applications, microwave devices, and integrated circuit components where high permittivity and low loss characteristics are required; the material is also investigated for piezoelectric and ferroelectric applications in research settings, offering potential advantages over more conventional dielectrics in miniaturized or high-frequency electronics.

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.
