Abstract
Dielectric constant (epsilon), loss (tan delta) and conductivity (sigm a) of ZnF2-PbO-TeO2 glasses (of composition 20, 10 and 70 by wt%) are measured as a function of frequency in the range 10(2)-10(7) Hz and in the temperature range 30-200 degrees C. The observations were repeate d for the chromium doped samples (0.04 and 0.06 wt%). The essential di fferences in the dielectric properties are pointed out and explained o n the basis of the point defects created by the glass network modifier s.
