抄録

Each aqueous solution of LiNO<SUB>3</SUB> and Al(NO<SUB>3</SUB>)<SUB>3</SUB> obtained by dissolving in a proper amount of distilled water was used as the starting solution, mixing them. γ-LiAlO<SUB>2</SUB> was synthesized by a sol-gel method from the starting solutions with each small amount of Si(OC<SUB>2</SUB>H<SUB>5</SUB>)<SUB>4</SUB> and the additives such as MnCl<SUB>2</SUB>, CoCl<SUB>2</SUB>, NiCl<SUB>2</SUB> or CuCl<SUB>2</SUB>. γ-LiAlO<SUB>2</SUB> 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-LiAlO<SUB>2</SUB> was observed in temperature range from 600° to 700°C. Each additive of MnCl<SUB>2</SUB> and CuCl<SUB>2</SUB> revealed the acceleration effect for the formation of γ-LiAlO<SUB>2</SUB> and in particular, CuCl<SUB>2</SUB> among the additives was most effective for its formation. Also, the addition of CuCl<SUB>2</SUB> ranging in the con-centration from 1.0×10<SUP>-3</SUP> to 4.5×10<SUP>-3</SUP> mol revealed the acceleration effect for the formation of γ-LiAlO<SUB>2</SUB> and that of CuCl<SUB>2</SUB> with a concentration of 3.5×10<SUP>-3</SUP> mol was especially most effective for its formation.
