The Li 4+xAl xSi 1-xO 4-yAl 2O 3 (x=0 to 0.5, y=0 to 0.5) ion conductors were prepared by the Sol-Gel method and examined in detail. The powder and sintered samples were characterized by TG-DTA, XRD, SEM, and AC impedance techniques. The experimental results show that the conductivity and sinterability increase with the amount of excess Al 2O 3 in the silicate. The particle size of the powder samples is about 0.13 μm. The maximum conductivity at 18 ℃ is 3.057×10 -5 s/cm for Li 4.4Al 0.4Si 0.6O 4-0.3 Al 2O 3.
