Abstract
Glasses from the system 15PbO-5Li2CO3-(80-x)B2O3-xAg2O (x=0.5,1,2 and 4) have been prepared by the melting quenching technique. Their physical and structural properties were accessed by means of XRD, FTIR, SEM and EDS. The prepared materials present a glass surface and amorphous nature. FTIR and Raman results indicate that silver oxide acts as a network modifier even at small quantities, by converting three coordinated to four coordinated borons. These results were evaluated by measuring the relative concentrations of BO3 and BO4 units in the glass matrix. Other physical properties, such as density are also affected by the silver oxide composition.
