· JVASP-23474· ErSiIr

ErSiIr is an intermetallic ceramic compound combining erbium, silicon, and iridium. This material belongs to the rare-earth intermetallic family and appears to be a research or specialized compound rather than a commodity material, likely investigated for high-temperature structural or functional applications where the combined properties of rare-earth elements and refractory metals are valuable.

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.
