摘要：

The electrical conductivity and conductivity relaxation of xNa(2)O-(100-x)TeO2 glasses have been investigated in the frequency range of 10 Hz-2 MHz and in the temperature range of 373-533 K and compared with the results of silicate and borate glasses. The Anderson-Stuart model was employed to explain the de activation energy. The relaxation behavior of these glasses was analyzed in the light of the modulus formalism. The variation of the stretched exponential parameter with composition was explained in terms of cation-cation distance correlation. Furthermore, the structural model of tellurite glasses was employed to explain the composition dependence of the conductivity relaxation time. [S0163-1829(99)07901-1].
