· JVASP-122882· Sm3Os

Sm₃Os is an intermetallic ceramic compound combining samarium (a rare-earth element) with osmium (a refractory metal), representing a high-density material in the rare-earth intermetallic family. This material is primarily explored in advanced research contexts for applications requiring extreme hardness, thermal stability, and corrosion resistance at elevated temperatures. While not yet widely commercialized in mainstream engineering, samarium–osmium compounds are investigated for specialized high-performance applications where conventional superalloys or ceramics reach their limits.

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.
