The density and molar volume of some phosphate glasses (xNa2O•(100-x)P2O5, x = 30, 35, 40, 45, 50); xB2O3•(1-x)NaPO3, x = 5, 10, 15, 20, 25; xNa2O•(30-x) K2O•10Al2O3• 25B2O3•35P2O5, x= 5, 10, 15, 20, 25) glasses were determined, in order to study their structure. The density of the glasses increased while their molar volume values decreases with the increase of sodium oxide content in phosphate glasses. The results obtained could be correlated to several factors such as the polarization, the field strengths and the ionic radii of the different incorporated cations
