· JVASP-104868· PmSmIr2

PmSmIr2 is an intermetallic ceramic compound combining promethium, samarium, and iridium—a rare-earth and refractory metal system explored primarily in research settings. This material belongs to the family of high-density intermetallics investigated for extreme-environment applications where thermal stability, oxidation resistance, and mechanical performance at elevated temperatures are critical. While not yet widely commercialized, compounds in this chemical family show promise for specialized aerospace and nuclear applications where conventional superalloys reach their limits.

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.
