· SiIrO3

SiIrO3 is an experimental ternary ceramic compound combining silicon, iridium, and oxygen—a mixed-metal oxide that belongs to the family of refractory and high-performance ceramics. This material remains primarily in research contexts, investigated for potential applications requiring exceptional thermal stability, chemical inertness, and the unique properties conferred by iridium's high density and catalytic character. The incorporation of iridium distinguishes it from conventional silicate ceramics and suggests potential value in extreme-environment applications where cost is secondary to performance.
