Electrical conductivity and dielectric constant of magnesium phosphate glasses
ac complex-impedance measurements were carried out on the prepared MgO-P 2O 5 glasses in the frequency range 0.1–100 kHz and temperature range 293–573 K. The low frequency Cole-Cole dependence of the Z″ ( Z′) impedance and the linear dependence of ϵ″ (ϵ′) dielectric constant revealed that the conduc...

2O
5 glasses in the frequency range 0.1–100 kHz and temperature range 293–573 K. The low frequency Cole-Cole dependence of the
Z″ (
Z′) impedance and the linear dependence of ϵ″ (ϵ′) dielectric constant revealed that the conduction mechanism in the present glass system is mainly ionic. The dc electrical conductivity, the activation energy and the relaxation energy are found to be sensitive to the glass composition. It is found from the obtained data that the MgO-P
2O
5 glass system can be divided into two compositional regions. |
