Lithium aluminate (LiAlO₂) is an inorganic ceramic compound combining lithium and aluminum oxides, commonly encountered as a crystalline solid. It appears in specialized applications requiring thermal stability and ionic conductivity, particularly in battery electrolytes, high-temperature ceramics, and as a component in advanced refractory materials. Engineers select LiAlO₂-based compositions for environments demanding chemical stability at elevated temperatures and low thermal expansion, though it is often used as a secondary phase or dopant rather than as a primary monolithic structure.
