The sodium borate glasses with fixed alkali content of 10 mole % and different
modifiers have been prepared. The concentration of the modifiers (PbO, Al2O3 and fly-ash)
has been kept at 5 mole % and results are compared with binary sodium borate glasses. From
the optical data, the optical band gap and cutoff wavelength were calculated and structural
changes induced by addition of these modifiers have been investigated by UV-VIS, FTIR
spectroscopy, XRD and density measurements. This work can lead to future utilization of fly-ash
in glass forming materials.
