· JVASP-50016· Ce3Y4O12

Ce3Y4O12 is a rare-earth ceramic compound combining cerium and yttrium oxides, belonging to the family of mixed rare-earth oxides with potential applications in high-temperature and ionic-conducting systems. This material is primarily investigated in research contexts for its thermal stability and potential use in solid-state electrolytes, thermal barrier coatings, and advanced refractory applications where rare-earth dopants enhance material performance. Its selection over single-component oxides or alternative rare-earth combinations depends on achieving specific combinations of thermal conductivity, ionic conductivity, and chemical stability demanded by next-generation energy and aerospace 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.
