· Nd2 Fe2 As2 O2

Nd₂Fe₂As₂O₂ is a layered oxypnictide semiconductor combining rare-earth (neodymium), transition metal (iron), and pnictogen (arsenic) elements in a mixed-valence structure. This material belongs to the broader family of iron-based oxypnictides, which are primarily of research interest for studying unconventional superconductivity, magnetism, and electronic structure in strongly correlated electron systems. Industrial applications remain limited; the material is encountered mainly in academic and exploratory device research rather than established commercial manufacturing.

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.
