· JVASP-50891· CeSmO2

CeSmO2 is a mixed rare-earth oxide ceramic combining cerium and samarium oxides, belonging to the family of fluorite-structure ceramics commonly explored for high-temperature and nuclear applications. This material is primarily investigated in research contexts for its potential in nuclear fuel matrices, solid-state electrolytes for advanced energy devices, and thermal barrier coatings where radiation tolerance and chemical stability are critical. Its rare-earth composition makes it notable for applications requiring resistance to neutron damage and high-temperature oxidation, positioning it as a candidate material for next-generation nuclear reactors and advanced ceramics where conventional oxides show limitations.

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.
