Structural study of density and refractive index of Sb2O3–B2O3 glasses
Source abstract
Abstract
Abstract Density, molar volume, refractive index and molar refraction have been correlated with the structural units in Sb 2 O 3 –B 2 O 3 glasses. It is proposed that these glasses include SbO 3 pyramids, BO 4 tetrahedra, symmetric- and asymmetric BO 3 units. Concentration of these units could be determined by using literature data of the fraction of four-coordinated boron atoms. Each of the structural units contributes to the studied properties by a factor that remains the same overall the entire composition region. Probable existence of certain fraction of Sb 5 + ions is discussed. It is deduced that the glasses can be treated by assuming the presence of SbO 3 as the sole structural unit of Sb 2 O 3 .
