Electric and Dielectric Properties of Magnesium Metaphosphate Glasses

Modulus formalism and dielectric relaxation in metaphosphate glass with MgO modifier using imaginary and real impedance measurements and dielectric relaxation spectroscopy are investigated. In the range of temperatures 721 – 822 K and over the range of frequency from 10 Hz to 2 MHz the electrical conductivity measurements were performed. Arrhenius conductivity activation energy calculated from DC measurements and the activation energies estimated from electric modulus and impedance AC measurements are in good agreement.
