SrZrO3
ceramic· SrZrO3
Strontium zirconate (SrZrO₃) is a perovskite ceramic compound valued for its high-temperature stability and refractory properties. It is used primarily in thermal barrier coatings for gas turbines, crucibles for metal casting, and as a component in advanced ceramics where chemical inertness and thermal shock resistance are critical. SrZrO₃ is notable among perovskite ceramics for its ability to maintain structural integrity at elevated temperatures and in chemically aggressive environments, making it preferred over oxides with lower melting points in demanding aerospace and metallurgical applications.

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.
