· JVASP-39984· MgSiIr2

MgSiIr2 is an intermetallic ceramic compound containing magnesium, silicon, and iridium. This is a research-phase material primarily of academic interest; limited industrial adoption exists due to the high cost and scarcity of iridium. The material belongs to the family of ternary intermetallics and refractory ceramics, and would be investigated for extreme-temperature applications or specialized catalytic environments where the combination of light magnesium, refractory silicon, and noble-metal iridium might offer unique property synergies.
