· JVASP-79591· IrN

Iridium nitride (IrN) is a refractory ceramic compound combining the noble metal iridium with nitrogen, belonging to the family of transition metal nitrides. It is primarily of research and developmental interest rather than established in high-volume manufacturing, valued for its exceptional hardness, high-temperature stability, and chemical inertness. IrN shows promise in extreme-environment applications where traditional ceramics or coatings would fail, particularly in aerospace, cutting tools, and protective coatings, though its cost and limited production currently restrict adoption to specialized or experimental systems.

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.
