· JVASP-16631· PrB2Ir3

PrB2Ir3 is an intermetallic ceramic compound combining praseodymium, boron, and iridium—a dense, refractory material belonging to the family of rare-earth transition-metal borides. This is primarily a research and development compound rather than a volume production material; it is studied for its potential in extreme-environment applications where high stiffness, thermal stability, and resistance to oxidation are required simultaneously.
