Glass samples of compositions xV2O5-(20-x)
MnO2-20PbO-60B2O3 with x varying
from 0 to 15 % mole fraction are prepared by melt quench technique. The structural analysis
of glasses is carried out by XRD, FTIR and density measurement techniques. The FTIR
spectral studies have pointed out the conversion of structural units of
BO3 to BO4 with the
presence of VO4 and VO5 structural units of vanadium in these glasses.
Due to the formation
of BO4 groups, an increase in density from 3.52 to 4.33 g··cm-3
for MnO2-PbO-B2O3 glasses is
observed with an increase in V2O5 content.
Keywords: borate glass; vanadium; FTIR; density
