The Estimation of Oxide Polarizability and Basicity using Electronegativity for B2O3:M2O Glass System (M=Li, Na, K, Rb)

D.B.Thombre

Glass samples of binary glass system [100-(x+10)] B2O3: (x+10) M2O; x take values in the step of 10, were prepared by conventional melt-quench technique. The concept of average oxide ion polarizability ( α0 2-), and optical basicity (Λ) are estimated by using electronegativity; for some binary oxide glasses. The value of the oxide ion polarizability, α0 2- (Reddy) has a good correlation with basicity, Λ(Duffy). The average electronegativity (χ1av) values are smaller than, oxide ion polarizability ( α0 2-), and basicity, Λ(Duffy) determined with increasing mol % of glass modifiers. It has a good correlation between α0 2- (Reddy), and Λ (Duffy). The present research is another trend of the oxide ion polarizability and basicity determined for binary glasses by using different glass modifier.
