· JVASP-40336· LiY2Ir

LiY₂Ir is a ternary ceramic compound combining lithium, yttrium, and iridium elements, representing an experimental composition in the family of mixed-metal oxide or intermetallic ceramics. This material remains primarily a research-phase compound with potential applications in high-temperature structural ceramics, advanced catalysis, or functional ceramics where the combination of rare-earth (yttrium) and noble-metal (iridium) constituents could offer thermal stability and chemical resistance; its true engineering relevance depends on phase stability, sintering behavior, and performance data that are not yet widely documented in industry practice.
