Electrical and dielectric properties of zinc lead Tellurite glasses with lead in various form

Original language description

Heavy metal oxide glasses containing lead are typically stable against devitrification upon heating and they have a wide infrared transmittance, up to the wavelength of 8 μm. Influence of the one constituent (PbO, Pb3O4, PbO2, PbF2, PbBr2, PbCl2, PbI2, Pb(NO3)2 and PbCO3) on DC conductivity, static permittivity, dielectric relaxation of ternary glasses of the 70 TeO2 - 10 ZnO - 20 PbX system is presented and discussed. DC conductivity values at constant temperature changes by two orders of magnitude depending on the form used. The conduction activation energy values of these glasses determined in temperature range from 20 to 200 °C are from 0.94 to 1.08 eV. In the case of the use of halides (Br-, Cl-) and Pb(NO3)2, the values of DC conductivity are the highest and the conduction activation energy increases significantly compared to other forms of Pb. Permittivity of the glasses slightly increases with temperature, and significantly increases with decreasing frequency of electric field. The permittivity values at constant temperature and frequency are significantly depending on the chemical form of Pb modifier.
