The Estimation of the Oxide Ion polarizability using the Electronegativity for B2O3-Li2O-Mo glass system

El Sayed Moustafa, Farid Elkhateb


Recently Optical electronegativity of many binary oxide glasses has been evaluated on the basis of two different parameters, the linear refractive index and the energy gap, which have demonstrated remarkable correlation. In the present study, an improvement method to estimate the oxide ion polarizability through the average optical electronegativity for the lithium borate metal (Mo) glass system has been proposed. The electronic oxide polarizability of our prepared ternary oxide glasses have been estimated on the basis of the average optical electronegativity. In other side the value of the oxide ion polarizability has been determined using the equation of Dimitrov based on the measured linear refractive index. The estimated values are in good agreement with the available experimental data. The present research is another trend of the oxide ion polarizability determination for ternary glasses.

Keywords: oxide ion polarizability , optical electronegativity ,ternary glasses.
