Description
The linear impedance of barium-vanadate glasses was measured. Samples of the composition of xBaO-(100-x)V2O5 where x= 30, 40 and 45 (in %mol) were prepared by the conventional melt quenching technique. Appropriate amounts of reagents: BaO (≥99.9%, P.P.H STANLAB Sp.J.) and V2O5 (≥99.9%, POCH) were thoroughly mixed in an agate mortar. The melting was performed in porcelain crucibles at 1273 K for 10–30 min, depending on glass composition. The melts were poured on preheated (to 393 K) brass plate and pressed by another plate to obtain flat circular pellets of 1-2 mm thickness and 10-20 mm in diameter.
For the electrical measurements gold electrodes were evaporated at the polished samples. Impedance measurements were carried out in the frequency range from 10 mHz to 1 MHz with the ac voltage of 1 Vrms in the temperature range from 153 K to 423 K with the Novocontrol Concept 40 broadband dielectric spectrometer.
