Abstract
The glass-forming region has been determined in the ternary system Li2O-PbO -P2O5. The thermal and electrical properties of xLi(2)O-(0.50-x)PbO-0.50P(2 )O(5) (0 less than or equal to x less than or equal to 0.50) have been stud ied. DSC measurements give the variation of T-g from 395 degreesC (for x = 0) to 302 degreesC (for x = 0.50). Ionic conductivity increases from 2.23 1 0(-7) (for x = 0.10) to 10(-3) Ohm (-1).cm(-1) (for x = 0.50) at 300 degree sC; the activation energy decreases from 1.05 to 0.71 eV on increasing lith ium content. Electrical and structural data are correlated. (C) 2001 Elsevi er Science Ltd. All rights reserved.
