Problem statement: In the present work, we applied the concept of the optical electronegativity to predict basic properties of some ternary oxide glasses. 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. Approach: In this study, the refractive indexhas beendetermined through the optical electronegativity and obtain a perfect

... inear correlation between the calculated refractive index and the estimated values using the dielectric constant value of the prepared samples. Results: The average electronic oxide polarizability and the interaction parameter of our ternary oxide glasses have been estimated on the basis of the average optical electronegativity. Conclusion: The estimated values are in good agreement with the available experimental data. The present research is an improvement of the optical electronegativity determination.
