· JVASP-25776· Li2AlBO4

Li2AlBO4 is an inorganic ceramic compound combining lithium, aluminum, and borate phases, belonging to the family of mixed-metal borates. This material is primarily investigated in research contexts for advanced ceramic applications where thermal stability, chemical durability, and controlled thermal expansion are critical; it has potential use in high-temperature applications, glass-ceramic systems, and as a component in specialized refractory or electronic ceramics, though it remains largely experimental rather than a commodity industrial material.
