Li 4SiO 4 x Eu 2O 3( x =0 00 to 0 15) ionic conductors were prepared by a Sol Gel method. Structure, shape, and ionic conductivity have been studied using DTA TG, XRD, TEM and AC impedance techniques. The experimental results show that Li 4SiO 4 can be synthesised at low temperatures using the sol gel method, and that its ionic conductivity is higher than that of the sample prepared by solid state reaction. Suitable Eu 2O 3 doping improves ionic conductivity of Li 4SiO 4.
