· In1 Si1 Ir1

InSiIr is a ternary intermetallic compound combining indium, silicon, and iridium in a 1:1:1 stoichiometric ratio. This is a research-phase material studied for its potential as a high-temperature structural intermetallic, leveraging iridium's exceptional thermal stability and oxidation resistance combined with indium and silicon's contributions to phase stability and density optimization. The material remains largely experimental and is of primary interest to advanced materials researchers exploring next-generation aerospace and high-heat applications where conventional superalloys reach their limits.
