Abstract
Each aqueous solution of LiNO3 and Al(NO3)3 obtained by dissolving in a proper amount of distilled water was used as the starting solution, mixing them. γ-LiAlO2 was synthesized by a sol-gel method from the starting solutions with each small amount of Si(OC2H5)4 and the additives such as MnCl2, CoCl2, NiCl2 or CuCl2. γ-LiAlO2 began to form at a temperature around 700°C and its formation was most remarkable at 1000°C of the heighest temperature used in this study. The phase transition from β-to γ-LiAlO2 was observed in temperature range from 600° to 700°C. Each additive of MnCl2 and CuCl2 revealed the acceleration effect for the formation of γ-LiAlO2 and in particular, CuCl2 among the additives was most effective for its formation. Also, the addition of CuCl2 ranging in the con-centration from 1.0×10-3 to 4.5×10-3 mol revealed the acceleration effect for the formation of γ-LiAlO2 and that of CuCl2 with a concentration of 3.5×10-3 mol was especially most effective for its formation.
