Ca₃(SiIr)₄ is an intermetallic ceramic compound combining calcium, silicon, and iridium in a fixed stoichiometric ratio. This is a research-phase material with no established commercial production; it belongs to the family of high-entropy and mixed-metal ceramics being explored for extreme-environment applications where conventional ceramics or superalloys reach thermal or chemical limits. The iridium content makes this a laboratory compound of interest for high-temperature stability and oxidation resistance, though practical engineering use remains limited to fundamental material science investigations.
