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.
