Description
Electrical properties were studied for borate-lead glasses and glass-ceramics doped with iron ions. Glass samples of composition of xFe2O3–(100 − x)(B2O3–2PbO) (2.5 b x b 37, in mol%) were prepared by the conventional melt quenching technique. The melting was conducted in alumina crucibles at the temperature of 1523 K. The melts were poured on a preheated (573 K) brass plate and pressed by an another plate to obtain flat circular samples of 1–2 mm thickness and 20–30 mm in diameter. The quenched pellets were annealed at the temperature of 673 K for 3 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 with the ac voltage of 1 V rms in the temperature range from 153 K to 423 K with the Concept 40 broadband dielectric spectrometer.
