Linear impedance of 1Si3N4–99(40Na2O-20CaO-40P2O5) glass measured with impedance spectroscopy method at low temperature region

Description

The linear electrical properties of  1Si3N4–99(40Na2O-20CaO-40P2O5) glass was measured by impedance spectroscopy method. 

The composition of 1Si3N4–99(40Na2O-20CaO-40P2O5) (in mol%) was prepared by the conventional melt quenching technique. Appropriate amounts of reagents: NaH2PO4 (≥99.5% SIGMA ALDRICH), Na2CO3 (99.9+% ChemPur GmbH) and CaCO3 (99.9+% ChemPur GmbH), Si3N4 (99.9+% ChemPur GmbH) were thoroughly mixed. Batches were melted in porcelain crucibles at temperatures of 850–950 degC for 30–60 min, in air atmosphere. Melt was poured on a brass plate. 

For the electrical measurements gold electrodes were evaporated at the preheated samples. Impedance measurements were carried out in the temperature range from 153 K to 423 K, in the frequency range from 10mHz to 1 MHz and with the ac voltage of 1 Vrms with Concept 40 broadband dielectric spectrometer.
