Ir4 Th2

Ir₄Th₂ is an intermetallic ceramic compound combining iridium and thorium, representing a refractory ceramic material designed for extreme-temperature applications. This material belongs to the family of high-melting-point intermetallics and is primarily investigated for aerospace and nuclear contexts where superior thermal stability and oxidation resistance are critical. The iridium-thorium system is notable for its potential in environments exceeding the limits of conventional superalloys and refractory metals, though it remains largely a research-stage material with limited commercial production.
