Ce2Dy2O7
ceramic· JVASP-30196· Ce2Dy2O7
Ce2Dy2O7 is a rare-earth oxide ceramic belonging to the pyrochlore family, combining cerium and dysprosium oxides in a stable crystalline structure. This material is primarily investigated for high-temperature thermal barrier coating (TBC) applications in aerospace and power generation, where its rare-earth composition offers improved thermal stability and lower thermal conductivity compared to conventional yttria-stabilized zirconia (YSZ). The cerium-dysprosium combination is notable for enhanced chemical durability in oxidizing and molten salt environments, making it particularly attractive for next-generation gas turbine engines and concentrated solar power systems operating at extreme temperatures.

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.
