Lithium-Lead-Bismuth phosphates glasses having, a composition 30Li(3)PO(4)-(70-x)Pb-3(PO4)(2)-xBiPO(4) (45 <= x <= 60 mol%) were prepared by using the melt quenching method 1000 degrees C. The thermal stability of theses glasses increases with the substitution of Bi2O3 with PbO. The ionic conductivity of all compositions have been measured over a wide temperature (200-500 degrees C) and frequency range (1-106 Hz). The ionic conductivity data below and above T-g follows Arrhenius and Vogel-Tamman-Fulcher (VTF) relationship, respectively. The activation energies are estimated and discussed. The dependence in frequency of AC conductivity is found to obey Jonscher's relation. (C) 2015 Elsevier Ltd. All rights reserved.
