· JVASP-15284· ErSi2Ir2

ErSi2Ir2 is an intermetallic ceramic compound combining erbium, silicon, and iridium elements, representing a research-phase material in the family of refractory intermetallics. This material class is investigated for extreme-temperature structural applications where conventional superalloys reach their limits, particularly in aerospace and energy sectors exploring next-generation powerplant designs. The combination of a rare-earth element (erbium) with the refractory metal iridium suggests potential for oxidation resistance and thermal stability, though ErSi2Ir2 remains primarily in experimental development rather than established industrial production.

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.
