templates, various precursors, and combustion processes. The main product in a solid state reaction is the phase; in a wet chemical reaction, the main product is a solid solution of and phases. The α-LiAlO2 modification (low temperature phase), with a hexagonal structure, undergoes transformation to the γ-modification (High temperature phase), with a tetragonal structure, at about 900 °C. The metastable β-modification, with a monoclinic structure, is assumed to transform to the γ-modification at about 900 °C. Natural occurrence The compound is unknown in the natural environment. However, a related compound, LiAl5O8, is known as the very recently discovered (as of 2020) and very rare mineral chukochenite. References Aluminates Lithium compounds
