· MgSi7Ir3

MgSi7Ir3 is an intermetallic ceramic compound combining magnesium, silicon, and iridium. This is a research-phase material within the family of refractory intermetallics, developed for applications requiring exceptional high-temperature stability and chemical resistance where conventional ceramics or superalloys reach their performance limits. The iridium content makes this a specialty material primarily of interest to aerospace and materials research communities exploring ultra-high-temperature structural applications.
