LiAlO 2 was prepared by two sol‐gel methods using simultaneous hydrolysis of the reagents: aluminum sec ‐butoxide/ lithium methoxide and aluminum sec ‐butoxide/LiOH. The resulting ceramic powders were compared with those prepared by two conventional methods (i.e., solid‐state fusion and peroxide). The sol‐gel method provided powders with a very high γ‐LiAlO 2 content after calcining at temperatures as low as 700°C when LiOH was used. The solids were characterized by AAS, DTA, TGA, XRD, and SEM.
