Abstract

Dielectric properties of some copper sodium phosphate glasses containing alumina have been studied in the frequency range from 1.05 to 100 kHz under vacuum (10-5torr). The dielectric parameters e.g. dielectric constant, dielectric loss, dielectric loss tangentand ac conductivity, have been calculated. The frequency dependence of the dielectric constant indicates the presence of dipole electric polarization due to linking of one Cu2+ ion with two non-bridging oxygens and ionic polarization due to the accumulation of sodium ions at the interfaces. The frequency dependence of the dielectric loss indicates that the conduction is a dominant contribution to the energy loss. The ac conductivity measurements exhibit the coexistence of electronic (due to the electron hopping from Cu+ to Cu2+ ions) and ionic (due to the mobility of sodium ions).
