ABSTRACT
Ion transport in Li2O–CaO–Bi2O3 glasses has been studied in the frequency range from 10 Hz to 2 MHz and in the temperature range from 293 to 543 K. The variation of the dc conductivity and the activation energy of these glasses with composition have been compared with those of binary lithium bismuthate glasses. It has been observed that the introduction of CaO in small amount does not effect the dc conductivity and the corresponding activation energy, but the larger amount of CaO changes them to some extent. The frequency-dependent conductivity has been studied using both conductivity and modulus formalisms. The values of the nonexponential parameter and frequency exponent are found to differ for the Li2O–CaO–Bi2O3 glasses from those for the binary Li2O–Bi2O3 glasses. The concentration of mobile Li+ ions does not change appreciably with the change in the Li2O as well as CaO content in the compositions. The increasing amount of CaO in the glass compositions for fixed Li2O content points out that CaO dilates the glass network, enhancing the migration of Li+ ions.
