· JVASP-38153· NdSmIr2

NdSmIr2 is an intermetallic ceramic compound combining neodymium, samarium, and iridium—a rare-earth transition metal system in the research phase. This material belongs to the family of high-density intermetallics being investigated for extreme environment applications, where its combination of refractory metals and rare-earth elements offers potential for high-temperature stability and specialized magnetic or catalytic properties. While not yet established in mainstream industrial production, compounds in this family are of interest to researchers exploring next-generation materials for aerospace, catalysis, or high-temperature structural applications where conventional alloys or ceramics reach their limits.
