The electrical and dielectric properties of ternary glasses in the Sb2O3-PbCl2-AgCl system were investigated across a broad temperature and frequency range. The study found that the DC conductivity significantly increases with increasing AgCl or PbCl2 content, and the activation energy of the conduction process decreases with the substitution of PbCl2 by AgCl. The influence of composition on the AC conductivity of the glasses was also discussed.
Electrical and dielectric properties of ternary glasses in the Sb2O3-PbCl2-AgCl system were investigated across a broad temperature and frequency range. The studied glass system is interesting since it possesses a high ionic conductivity. The (Sb2O3)(x)-(PbCl2)(100 -y)(-)(x)-(AgCl)(y) glasses were prepared by melt-quenching method from high purity components. Different batches of these glasses were investigated with varying molar content of both Sb2O3 (45 <= x <= 70 mol %) and AgCl (5 <= y <= 25 mol %). The colour of the prepared chloro-antimonite glasses varies between yellow and brown. The glass transition temperature (T-g) decreases with increasing AgCl concentrations. DC and AC electrical conductivities and complex electrical modulus were measured across a temperature range from room temperature up to 200 degrees C and across a frequency range between 0.2 and 10(5) Hz. The dependence of DC conductivity on temperature follows the so-called Arrhenius-like equation. The DC conductivity at constant temperature significantly increases with increasing AgCl or PbCl2 content. It was found that the activation energy of conduction process decreases with the substitution of PbCl2 by AgCl from 1 eV down to 0.56 eV for (Sb2O3)(50)-(PbCl2)(45)-(AgCl)(5) and (Sb2O3)(50)-(PbCl2)(25)-(AgCl)(25), respectively. The influence of the composition on the AC conductivity of the investigated glasses is also discussed.
