The thermoelectric power above room temperature of the unconventional
lead vanadate glass is reported. It has been observed that the thermoe
lectric power shows weak variation with temperature and its magnitude
decreases with increase in V2O5 content in the glass compositions. Hei
kes' formula for the thermoelectric power can give an adequate explana
tion for the experimental data. Thermoelectric power data also give in
formation for the formation of small polarons in these glasses.
