FTIR spectral analysis on heavy metal borate glasses

Abstract

Inorganic heavy metal borate glasses were prepared through the melt quenching technique. Two sets of glasses were prepared, the compositions are (wt.%) 35Bi2O3+(50-x)B2O3+15Na2O+xPbO, where x=0, 10, 20, 30 and 35MO+30Na2O+35B2O3 (MO=Bi2O3, PbO, ZnO). The FTIR structural analysis was made. These glasses have different borate groups and it mainly depends on the modifier/metal ion concentration. The influence of heavy metal and transition metal ion on the borate network were also identified.
