· JVASP-103487· ErUN2

ErUN₂ is a ceramic compound in the rare-earth nitride family, combining erbium with nitrogen in a defined stoichiometric ratio. This material belongs to a class of refractory ceramics being investigated for extreme-environment applications where conventional oxides or carbides reach their thermal or chemical limits. As a research-grade material, ErUN₂ is notable for its potential high hardness, chemical inertness, and stability at elevated temperatures, making it a candidate for next-generation coatings and structural applications in nuclear, aerospace, or wear-resistant contexts where rare-earth nitrides offer advantages over traditional ceramic alternatives.

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.
