ceramic· JVASP-50506· Er2Zr2O7
Er₂Zr₂O₇ is a rare-earth zirconate ceramic compound belonging to the pyrochlore oxide family, composed of erbium and zirconium oxides. This material is primarily investigated as a thermal barrier coating (TBC) candidate and advanced refractory for high-temperature applications, particularly in aerospace and power generation contexts where superior thermal insulation and oxidation resistance are critical. Its appeal over conventional zirconia-based coatings lies in its potential for improved thermal stability at ultra-high temperatures and reduced sintering rates, making it relevant for next-generation gas turbine engines and hypersonic vehicle components.

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.
