Özet
The electrical and dielectric properties of three series of glasses, xHfO2–(40 − x)Fe2O3–60P2O5, 0 ≤ x ≤ 8 mol%, xCeO2–(40 − x)Fe2O3–60P2O5, 0 ≤ x ≤ 8 mol%, and xHfO2–(38 − x)Fe2O3–2B2O3–60P2O5 2 ≤ x ≤ 6 mol%, have been investigated by impedance spectroscopy over a wide frequency and temperature range. As expected, these glasses exhibit polaronic conductivity which strongly depends on the fraction of ferrous ions, Fe2+/Fetot. Following a detailed discussion on the DC conductivity, we use the MIGRATION concept to model their conductivity spectra. It is found that in each series of glasses, the shape of the conductivity isotherms remains the same indicating that the time-temperature superposition principle is satisfied and that the mechanism of conductivity is the same. Returning to a model-free scaling procedure, namely Summerfield scaling, it is found that while conductivity isotherms for …
