PbO-P2O5-As2O3 glasses containing
different concentrations of Al2O3 ranging from 0 to 5 mol%
were prepared. Dielectric properties (viz., dielectric constant
, loss tan 
and a.c. conductivity 
over a moderately wide range of frequency and temperature and
dielectric breakdown strength in air medium), optical properties (optical
absorption, IR spectra and thermoluminescence) and differential thermal
analysis have been studied. The interesting changes observed in these
studies have been explained in the light of different structural groups of
aluminium ions.
