Li2 Y4 Si4
semiconductor· Li2 Y4 Si4
Li₂Y₄Si₄ is an inorganic compound combining lithium, yttrium, and silicon that belongs to the rare-earth silicate family. As a research-phase material, it is primarily of interest in solid-state ionics and advanced ceramics development, where lithium-containing silicates are explored for applications requiring ionic conductivity or thermal stability at elevated temperatures. This material represents the broader family of rare-earth doped ceramics being investigated for next-generation solid-state battery electrolytes, thermal barrier coatings, and high-temperature structural applications where conventional oxides reach performance limits.
