Ionic conductivity in borate glasses with three types of mixed alkali cations

Physical and optical studies in mixed alkali borate glasses with three types of alkali ions

“…To the best of our knowledge dynamic conductivity spectra of few Li-Na-K-containing borate glasses have been reported [25][26][27]. More recently, Kim et al [28] reported the results of the composition dependence of the ionic conductivity in borate glasses with three types of mixed alkali cations.…”

Oxygen-Vacancy-Related Electrical Properties of 2CaTiO3–SiO2Glass

“…Figure 7 displays the dc conductivity and the peak frequency, obtained from the impedance complex Cole-Cole fitting. The dc and ac activation energies (E dc , E ac ) are obtained from the following Arrhenius relationships [12][13][14][15] .…”

Ionic transport in mixed-alkali glasses: hop through the distinctly different conduction pathways of low dimensionality

“…We present evidence that the real process of ionic transport in both the SA glass and the MA glass systems can be described by the fractional kinetic equations containing non-integer integration/differentiation operators. To do this, we report the ac conductivity, in addition to the previous measurements of the dc conductivity [12][13][14], in a series of MA borate glass systems (Li 1−x A x ) 2 B 4 O 7 (A = Na, K, Rb, Cs) at various temperatures, where x = 0, 0.2, 0.3, 0.5, 0.7, 0.9 and 1.0. The power-law exponent β in the SA and the MA borate glasses is analyzed in detail.…”
