· Li1 Al3 Si9 N14 O2

Li₁Al₃Si₉N₁₄O₂ is an oxynitride ceramic combining lithium, aluminum, silicon, nitrogen, and oxygen—a compound that bridges traditional silicate ceramics and advanced nitride systems. This material belongs to the family of rare-earth-free oxynitride ceramics currently under research for high-temperature structural applications where thermal stability and lightweight performance are critical. Engineering interest centers on potential applications in aerospace propulsion and thermal management systems where its mixed bonding character (ceramic oxide-nitride) may offer improved fracture resistance and thermal shock resistance compared to conventional alumina or silicon nitride.
