Description
The linear impedance of vanadate glass-ceramics containing BaTiO3 was measured. Samples of the composition of x[BaO,TiO2]–(80 − x)V2O5–20Bi2O3 where x = 5, 10 and 15 in mol% were prepared by a conventional melt quenching technique. The melting was performed in alumina crucibles at the temperature of 1273 K–1373 K. The melts were poured on a preheated (573 K) brass plate and pressed by another plate to obtain flat circular pellets of 1–2 mm thickness and 10–20 mm in diameter. Next subset of as-quenched samples was heat treated in air at the temperature of 633 K (close to the crystallization temperature) for 6 h and cooled with the furnace. For the electrical measurements gold electrodes were evaporated at the preheated samples. Impedance measurements were carried out in the frequency range from 1 mHz to 1 MHz and the temperature range from 153 K to 423 K, with the ac voltage of 1 Vrms with Concept 40 broadband dielectric spectrometer.
