HfSnIr

HfSnIr is a ternary intermetallic compound combining hafnium, tin, and iridium—a ceramic-class material in the refractory metal family. This is primarily a research material studied for ultrahigh-temperature structural applications where extreme thermal stability and chemical inertness are critical; it belongs to the broader class of high-entropy and intermetallic ceramics being developed to replace traditional nickel-based superalloys in next-generation aerospace and power-generation environments.
