· JVASP-37237· SmYIr2

SmYIr2 is a ternary intermetallic ceramic compound combining samarium, yttrium, and iridium. This material belongs to the family of rare-earth iridium compounds, which are primarily investigated in research contexts for high-temperature structural applications and potential catalytic properties due to the combination of refractory metals and rare-earth elements. Materials in this class are notable for their thermal stability and density, making them candidates for aerospace and advanced energy applications where conventional ceramics or superalloys reach their limits.
