· Sm1 Ni2 As2

Sm₁Ni₂As₂ is an intermetallic compound combining samarium (a rare-earth element), nickel, and arsenic in a layered crystal structure. This is a research-phase material studied primarily for its potential thermoelectric and magnetoelectronic properties rather than established industrial production. The material belongs to the family of rare-earth pnictides, which are of interest to materials scientists exploring next-generation energy conversion and magnetic devices where conventional semiconductors or intermetallics reach performance limits.

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.
