The Li 4.4Al 0.4Si 0.6O 4-xLi 3BO 3 (x=0 to 0.5) ion conductors were prepared by the sol-gel method. The powder and sintered samples were characterized by DTA-TG, XRD, SEM and ac impedance techniques. The temperature of the preparation of powder patterns decreased by this method as compared to that of the preparation in solid state reaction. The conductivity and sinterability increased with Li 3BO 3 increasing from x=0 to 0.2 in the Li 4.4Al 0.4Si 0.6O 4-xLi 3BO 3 solid electrolytes. The particle size of the sintered pellets is about 0.12 μm. The maximum conductivity at 20 ℃ is 3.165×10 -5 S·cm -1 for Li 4.4Al 0.4Si 0.6O 4-0.2Li 3BO 3.
