Linear impedance as a function of A.C. voltage for 50(2Bi2O3-V2O5)-50SrB4O7 glass-ceramic heat-treated at 813 K measured with impedance spectroscopy method at high temperature region
Description
The linear electrcial properties as a function of A.C. voltage of 50(2Bi2O3-V2O5)-50SrB4O7 glass-ceramic heat treated at 813 K was measured by impedance spectroscopy method.
The polycrystalline strontium–borate, SrB4O7 was synthesized via a solid state reaction route that involved heating stoichiometric mixtures of analytical grade SrCO3 and H3BO3 at 1073 K for 12 hours. Next, sample of a composition of 50(2Bi2O3-V2O5)-50SrB4O7 (in %mol) was prepared from reagent-grade Bi2O3, V2O5 and preprepared SrB4O7. Samples of glass were prepared by the conventional melt quenching technique. The melting was conducted in alumina crucibles at 1373 K for 2 hours. The melt was poured onto a preheated (573 K) brass plate and pressed by another plate to obtain flat circular disks of 1–2 mm thickness and 20–30 mm in diameter. Glass was heat treated at 813 K to obtain glass-ceramic.
For the electrical measurements gold electrodes were evaporated at the preheated samples. Impedance measurements were carried out in the temperature range from 373 K to 813 K, with the ac voltage varied from 0.01 Vrms to 2 Vrms and frequency range from 1 mHz to 1MHz with Concept 40 broadband dielectric spectrometer and a high temperature Controller Novotherm HT 1600. The measurements were carried out both while increasing and decreasing the temperature.
