· JVASP-157228· Pr2IrRu

Pr2IrRu is an intermetallic ceramic compound combining praseodymium, iridium, and ruthenium—a high-entropy ceramic material designed for extreme-temperature and chemically harsh environments. This is primarily a research-phase material investigated for its potential in aerospace propulsion systems, nuclear applications, and high-temperature structural components where conventional superalloys reach their thermal limits. The combination of precious metals (Ir, Ru) with rare-earth elements (Pr) targets superior oxidation resistance, thermal stability, and mechanical performance at temperatures where ceramic matrix composites and single-crystal superalloys become impractical.

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.
