Preparation and electrical characterization of NASICON-type compound, Li1.3Ge1.4Ti0.3Al0.3(PO4)3, are described. The solid solution is obtained with Ge4+ → Ti4+ and Ge4+ → Al3+ substitutions in LiGe2(PO4)3. The powder has been fabricated by a solid state reaction and the structural characteristics of it have been studied by X-ray. Ceramic samples have been sintered by varying the sintering duration from 1 to 3 h. Samples were studied by complex impedance spectroscopy in the frequency range 1 MHz–1.2 GHz and temperature range 300–600 K. Two regions of relaxation dispersion were found. The dispersions were related to the fast Li+ ion transport in the grains and grain boundaries. Variation of the sintering duration has no considerable effect on electrical properties of the ceramics.
