Study of Physical Properties of Sodiumborophosphate Glasses

M. D. Thombre

Abstract :

Glass samples of the Sodium borophosphate 42.5Na2O• (57.5–x) B2O3–xP2O5, x=0–57.5 in the step of 5.75, were prepared by conventional melt–quench technique. In order to study structure, The physical parameters like, Average molecular weight , Density , Molar volume , Oxygen packing density, Ionic Concentration , Inter ionic distance ,and Polaron radius were determined. Average molecular weight, Molar volume, Inter ionic distance, and Polaron radius are increasing; where as Oxygen packing density, and Ionic Concentration decreases with increasing the mol% of P2O5. The density of the glasses increased while their molar volume values decreases. Molar volume increases linearly as mol % of P2O5 increases. Oxygen packing density is exactly apposite to that of molar volume. Ionic concentration decreases, where as inter ionic distance and polaron radius increases with increases the mol % of P2O5, respectively. Inter–ionic separation & polaron radius, Molar refractivity & Molar polarizability are also increases parallel with increase in mol% of P2O5. Inter–ionic distance, Polaron radius and molar refraction, molar polarizability varies linearly.
