Preparation And Ionic Conductivity Of Nanometer_Sized Li 2+X Gd X Si 1+X O 3 By The Sol_Gel Method, Rufen Chen, Xiuqin Song, Huating Liu

Journal of Electrochemistry

Li 2+x Gd xSi 1-x O 3( x =0～0.15) samples have been prepared by the Sol_Gel method. The power samples were characterized by DTA_TG, XRD and TEM. Ionic conductivity of the sinter was determined by means of A_C impedance measurements. The experimental results showed that the range of solid_solution was 0< x ≤0.09, while the conductivity of samples raised with increasing amount of Gd 2O 3 added, and average grain size of samples was 80 nm. In comparing with the samples by the conventional solid state reaction, the samples prepared by Sol_Gel method required lower temperature and presented higher ionic conductivity.
