· JVASP-49756· Dy2Zr2O7

Dy2Zr2O7 is a dysprosium zirconate pyrochlore ceramic compound belonging to the rare-earth zirconate family. This material is primarily investigated in research contexts for thermal barrier coating (TBC) applications in high-temperature aerospace and power generation environments, where it offers potential advantages over conventional yttria-stabilized zirconia (YSZ) in terms of phase stability and thermal conductivity at extreme temperatures. The pyrochlore structure and rare-earth dopant provide tailored thermal and mechanical properties for engines operating above 1200°C, though commercial adoption remains limited compared to established coating systems.

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.
