| description | The phosphate glasses, with composition (60-x)P2O5-25ZnO-(15+x)Li20 where 0.0 ≤
x≤ 5.0 mol% are prepared by conventional melt quenching method. The amorphous
nature of the glass is determined by X-Ray Diffraction (XRD). The DC
measurements are done by using four point probes and hence the activation energies
are determined. Arrhenius plot shows straight line behavior as observed that
confirmed the conductivity increased with Li2O content. The activation energy is
found to decreases from 0.75 eV to 0.08 eV as Li2O content is increased in the
temperature range from 310 K to 420 K. Measurements of the thermal conductivity
using Lee's disc apparatus have been made. It is observed that the maximum and
minimum thermal conductivity are 0.2679 Wm-1K1 and 0.2168 Wm-1K1
respectively. |
