Glasses in the system xB(2)O(3)-(60-x)P(2)O(5)-40Na(2)O (x = 0 mol. %, 10 mol. %, 20 mol. %, 30 mol. %, 40 mol. %) were prepared and characterized by measuring their density (rho), molar volume (V(M)), glass transition/softening temperature (T(g)/T(d)), thermal expansion coefficient (alpha) and chemical durability (DR). All of these values were found to vary with the B(2)O(3) content of the glasses. The results were interpreted on the basis of the structural data. The Raman and infrared spectra confirmed these structural changes.
