Abstract
Abstract
[ To study various properties of cobalt cations on glasses, a new borate 62B2O3-(20-x)ZnO-18Na2O-x CoO glass system, with x = 1.5,1,0.5 and 0 mol.% was prepared by using the melt quenching technique. Traditional methods and usual formulas were used to calculate the molar volume (Vm) and measurement of density (ρ).Optical bascity (Λth) was determined using the formula suggested by Duff and Ingram. The dependence of density (⍴), molar volume (Vm), ion concentration (N), polaron radius (rp), field strength (F), inter atomic distance (ri) ,optical bascity(Λth), electronic polarizability (α0−2) and electronegativity (Χav) on Co2+cations content were analyzed. The trend of density, field strength, ion concentration, electronegativity with composition shows an increasing behavior with CoO content, while molar volume, inter atomic distance, polaron radius, optical basicity and electronic polarizability exhibit a decrement behavior . so that these obtained results nominate these cobalt-borate glasses for promising applications such as optical devices. ]
