SiIr is a ceramic intermetallic compound combining silicon and iridium, representing a high-density material system typically explored for extreme-environment applications. This material belongs to the family of refractory ceramics and metal-ceramic composites, offering exceptional hardness and thermal stability characteristic of iridium-based compounds. SiIr is primarily of research and specialized industrial interest, used in applications demanding superior wear resistance, high-temperature strength, and chemical inertness where cost and fabrication complexity are secondary concerns.
