Glass samples of the system: xB{sub 2}O{sub 3}−(100−x) TeO{sub 2}; x= 15, 20, 25 and 30 mol% were prepared by melt quenching and characterized by X-ray diffraction, density measurements, Differential Scanning Calorimetry and FTIR spectroscopy. XRD confirmed the amorphous structure of all samples. Density of glasses decreased with increase in B{sub 2}O{sub 3} concentration due to the replacement of heavier TeO{sub 2} with lighter B{sub 2}O{sub 3} whereas the glass transition temperature increased from 339°C to 366°C; the later effect was due to increase in the concentration of stronger B-O bonds in the glass network. FTIR studies found that BO{sub 4} units convert into BO{sub 3} with the addition of B{sub 2}O{sub 3}.
