· JVASP-79110· Sm2Mg

Sm₂Mg is an intermetallic ceramic compound combining samarium (a rare-earth element) with magnesium, belonging to the family of rare-earth magnesium ceramics. This material is primarily explored in research contexts for high-temperature structural applications and advanced functional ceramics, where rare-earth reinforcement can improve thermal stability and oxidation resistance compared to conventional magnesium ceramics. Its potential lies in aerospace and automotive thermal management where lightweight, thermally stable intermetallics are needed, though industrial-scale deployment remains limited pending further development of processing methods and cost optimization.

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.
