· JVASP-41021· Ho2IrRh

Ho2IrRh is a ternary intermetallic compound combining holmium, iridium, and rhodium—a rare-earth transition metal ceramic typically studied for high-temperature structural and functional applications. This material belongs to the family of refractory intermetallics and is primarily encountered in research settings exploring advanced materials for extreme environments; its notable density and multi-metal composition position it as a candidate for applications demanding thermal stability, oxidation resistance, and mechanical integrity at elevated temperatures where conventional superalloys reach their limits.
