· 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.
