%X Melt quenched ”°SnO2(50-x)PbO:50V2O5”± glass system containing x = 5, 10, 15 in molar ratio has
been investigated. Effects of heating rate, glass transition, crystallization, melting temperature
and infrared spectra of SnO2 substituted PbO-V2O5 glass system are reported. XRD results show
that perfect vitrification has been achieved for all the glass samples after annealing at 150”ćC. DSC
results have indicated that eutectic composition of the lead metavanadate has been maintained for
all the glass systems up to 15 mole% of substitution. IR spectra for a SnO2 substitution of 5 mole%
V=O stretching frequency occur at 966 cm<sup>-1</sup> without appearance of any additional peak. But for 10
mole% and 15 mole% SnO2 substituted samples, additional peaks appear at 1023 and 1005 cm<sup>-1</sup>
indicating the effect of SnO2 in the vanadate crystalline matrix such that there is an elongation of
V=O bond. Since the crystalline matrix is affected, we can expect similar effect in the glass matrix
also.
