· JVASP-56230· SmMg2Ni9

SmMg2Ni9 is an intermetallic compound in the samarium-magnesium-nickel system, combining rare-earth and transition metals to form a complex crystalline structure. This material is primarily of research interest in hydrogen storage and battery applications, where the intermetallic phase can reversibly absorb and release hydrogen, making it a candidate for advanced energy storage systems and metal hydride technologies. Compared to conventional nickel-metal hydride formulations, rare-earth intermetallics like SmMg2Ni9 offer the potential for improved cycle life and modified thermodynamic properties, though commercial deployment remains limited and development is ongoing in academic and specialized industrial settings.

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.
