· JVASP-147255· Ce2Y2O7

Ce2Y2O7 is a rare-earth oxide ceramic compound combining cerium and yttrium oxides, belonging to the pyrochlore or fluorite-structure family of ceramic materials. This material is primarily investigated in research and emerging applications for its thermal stability, ionic conductivity, and resistance to sintering degradation at high temperatures. It is notable in thermal barrier coating systems and solid-state electrolyte development, where alternatives like yttria-stabilized zirconia (YSZ) may suffer from phase instability or lower conductivity, making rare-earth combinations attractive for next-generation high-temperature and electrochemical 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.
