· As3Ir

As₃Ir is an intermetallic ceramic compound combining arsenic and iridium, belonging to the family of refractory intermetallics studied for high-temperature structural applications. This material is primarily of research and developmental interest rather than widespread commercial use, with potential applications in extreme-temperature environments where conventional ceramics or superalloys reach their limits. Its appeal lies in the combination of a refractory metal (iridium) with a covalent network-forming element (arsenic), positioning it as a candidate for next-generation thermal barriers, aerospace components, or specialized chemical/thermal environments where both hardness and oxidation resistance are critical.
