· JVASP-19779· SmO

Samarium monoxide (SmO) is a rare-earth ceramic compound belonging to the rock-salt structure family of oxides. It is primarily studied in research and advanced materials applications rather than established industrial production, with potential utility in high-temperature ceramics, optical coatings, and specialized electronic devices. SmO is notable within the rare-earth oxide family for its thermal stability and potential applications in environments requiring materials resistant to oxidation and thermal cycling, though adoption remains limited compared to more developed rare-earth ceramics like yttria or ceria.

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.
