摘要：

Samples of Li7La3Zr2-0.75xAlxO12 (x = 0.00, 0.05, 0.10, 0.15, 0.20, 0.25, 0.30) were synthesised using the citrate-nitrate method. The crystal structure of each sample was characterised using X-ray diffraction. Doping the samples with Al reduced the synthesis time. The cubic modification of Li7La3Zr2O12 was obtained by treatment at 1150 degrees C for 1 h. The conductivity of the ceramic samples was studied by complex impedance spectroscopy at 25-230 degrees C. The composition with x = 0.15 had the highest total conductivity, 3.4.10(-4) S cm(-1), at 25 degrees C. (C) 2013 Elsevier B.V. All rights reserved.
