· JVASP-75781· MgAsIr2

MgAsIr2 is an intermetallic ceramic compound combining magnesium, arsenic, and iridium in a fixed stoichiometric ratio. This is a research-phase material with limited industrial deployment; it belongs to the family of ternary intermetallics and represents an exploratory composition where the iridium content imparts hardness and chemical stability while magnesium offers potential density advantages. Industrial interest in such compounds stems from high-temperature structural applications and specialized electronic or catalytic roles where conventional ceramics or superalloys fall short, though MgAsIr2 remains primarily a laboratory material under investigation for feasibility rather than an established engineering choice.
