· JVASP-122832· Sm3C

Sm3C is a rare-earth carbide ceramic composed of samarium and carbon, belonging to the family of lanthanide carbides used primarily in high-temperature and specialized applications. This material is valued in aerospace and nuclear contexts for its thermal stability and refractory properties, though it remains less common than other rare-earth ceramics and is often encountered in research or specialized industrial settings where its unique combination of thermal and chemical resistance offers advantages over conventional alternatives.

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.
