· JVASP-19082· BaTi2O5

Barium titanate (BaTi₂O₅) is an oxide ceramic compound belonging to the perovskite-related family, notable for its high dielectric and ferroelectric properties. It is primarily investigated in research and specialized applications for capacitors, piezoelectric devices, and electroceramics where high permittivity and coupling coefficients are advantageous. This material competes with other barium titanate phases and lead-based ceramics in applications requiring compact energy storage or electromechanical actuation, though its specific stoichiometry (BaTi₂O₅) is less common industrially than the standard BaTiO₃ perovskite.

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.
