· JVASP-40671· Li2Cr5Si4O14

Li2Cr5Si4O14 is a lithium chromium silicate ceramic compound that combines lithium, chromium oxide, and silicate components to form a dense crystalline structure. This material is primarily of research interest for high-temperature applications and advanced ceramics development, where the chromium and silicon oxide phases provide thermal stability and mechanical integrity. The lithium component offers potential benefits for thermal expansion matching and ionic properties, making it a candidate for specialized applications in refractory systems, thermal barrier coatings, or functional ceramics where conventional oxides are insufficient.
