· JVASP-149604· SmCoSi2

SmCoSi₂ is an intermetallic compound combining samarium, cobalt, and silicon, belonging to the rare-earth transition metal silicide family. This material is primarily of research interest for high-temperature applications and magnetic applications, as the samarium-cobalt base provides potential for enhanced strength and thermal stability, while the silicide structure offers oxidation resistance. SmCoSi₂ and related rare-earth silicides are being investigated for aerospace components, magnetic devices, and high-temperature structural applications where conventional alloys reach their limits, though industrial adoption remains limited compared to established superalloys and permanent magnets.

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.
