Abstract

There were investigated optical transmittance and direct electrical conductivity of the glass systems of TeO2 - Sb2O3 -PbCl2. Optical transmittance measured in the wave range of (2.5 – 7.5) μm depends significantly on the amount and the nature of defects of glasses and the glass composition. The highest value of optical transmittance was found for glass of the composition of 40 TeO2 - 10 Sb2O3 - 50 PbCl2. Direct electrical conductivity in the temperature range of (20 – 240) °C has the constant value of activation energy (~ 1.1 eV) if glasses own the low concentration of PbCl2. If the concentration of PbCl2 is increased then the change of value of activation energy at the temperature ~ 80°C was observed. The values of conductivity of the system TeO2 - Sb2O3 -PbCl2 are strongly affected by the concentration of PbCl2..
