· JVASP-1279· LuN

Lutetium nitride (LuN) is a refractory ceramic compound combining lutetium, the heaviest stable rare-earth element, with nitrogen in a rock-salt crystal structure. This material is primarily studied in research and advanced development contexts for extreme-environment and high-performance applications where thermal stability, hardness, and chemical inertness are critical.

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.
