Ionic Conductivity in Lithium-Borate-Tantalate Compound Glasses

We have investigated the ionic conductivity and dielectric relaxation in Li 2 B 4 O 7 (LBO) and Li 2 OB 2 O 3 -Ta 2 O 5 (LBTO) glasses. The sample was synthesized by using the melt quenching method. The frequency dependence of the electrical data from the LBO and LBTO glasses has been analyzed in th...

Summary:We have investigated the ionic conductivity and dielectric relaxation in Li 2 B 4 O 7 (LBO) and Li 2 OB 2 O 3 -Ta 2 O 5 (LBTO) glasses. The sample was synthesized by using the melt quenching method. The frequency dependence of the electrical data from the LBO and LBTO glasses has been analyzed in the frameworks of the impedance Cole-Cole formalism and the universal power-law representation driven by the modified fractional Rayleigh equation. The potential barriers in the LBO and the LBTO glasses turn out to be the same. Comparing with the dc and ac activation energies of the LBO glass, these energies of the LBTO glass decrease due to the increasing Coulomb interaction of inter-cationic interaction.
