摘要：

The dielectric properties of the 13.5 Na2S - 32.5 V2O5-54 P2O5 glass was thoughtfully examined after the glass was traditionally quenched and thermally treated for different treatment durations of 4, 6 and 12 h. Ac impedance spectroscopy, dielectric constant, loss tangent and electric modulus were all studied for various frequencies ranging from 500 Hz to 1 MHz and at temperatures from 303 to 573 K. The 12 h glass-ceramic nanocomposite exhibited the highest conductivity compared to other samples. The activation energy for con-ductivity, W, and for relaxation processes, E tau, are obtained where both values are in the range of (0.498-0.414 eV). The stretched exponent beta was estimated to be in the range of (0.82-0.93) indicating a Non-Debye type relaxation process.
