Research ArticleOpen accessEvery word in the titleNew approach between the Optical Basicity and the Dielectric Constant through the Molar Polarizability for Some Binary GlassesEl-Sayed MoustafaProblem statement: In the present study, a new correlation between the optical basiciry which describes the electronic charge clouds around the oxide glass and the dielectric constant has been proposed through the molar polarizability of the binary oxide glasses. Approach: Two experimental forms have been suggested relating the optical basicity and the molar electronic polarizability. Hence, the dielectric constant and … …Physics International, Vol. 2, Issue 1 · 26 Oct 2011 · 7,764 accessesView PDFCite
