· JVASP-12869· Li5AlO4

Li5AlO4 is a lithium aluminate ceramic compound belonging to the family of mixed-oxide ceramics with potential applications in electrochemical and thermal systems. This material is primarily of research interest rather than a widely commercialized engineering ceramic, with investigation focused on its properties as a solid electrolyte material and thermal component for advanced energy storage and high-temperature applications. Engineers would consider this compound for specialized applications requiring lithium-ion conductivity or thermal stability in demanding environments where conventional ceramics are insufficient.
