Li1.3Al0.3 (-) xScxTi1.7(PO4)(3) (where x = 0, 0.1, 0.15, 0.2, 0.3) lithium ionic conductors were prepared by Pechini process. Single NASICON-type phase was detected by X-ray powder diffraction analysis for all synthesized compounds. Ceramic samples have been sintered and investigated by impedance spectroscopy in broad frequency and temperature ranges. The dispersions of electrical parameters correspond to lithium ion migration in the bulk and possibly two different grain boundaries of the ceramics. (C) 2012 Elsevier B.V. All rights reserved.
