Ba3Zr2O7
ceramic· Ba3Zr2O7
Ba₃Zr₂O₇ is a ceramic oxide compound belonging to the family of barium zirconate materials, known for their high thermal stability and low thermal conductivity. This material is primarily of research and development interest for thermal barrier coating (TBC) systems in advanced gas turbines and aerospace engines, where it offers potential advantages over conventional yttria-stabilized zirconia in extreme high-temperature environments. Its notable characteristics include resistance to sintering at elevated temperatures and chemical stability, making it particularly attractive for next-generation propulsion systems operating above conventional TBC limits.

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.
