Linear impedance of 40Na2O-20CaO-40P2O5 glass measured with impedance spectroscopy method at low temperature region

Description

The linear electrical properties of  40Na2O-20CaO-40P2O5 glass was measured by impedance spectroscopy method. 

The glass composition of 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) 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. The exact composition of melted samples was tested with the use of SEM-EDS and was found to be Na18.5Ca5P16.8O59.5 (in at%).

For the electrical measurements gold electrodes were evaporated at the preheated samples. Impedance measurements were carried out in the temperature range from 213 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.
