Dielectric Constant of Sodium Silicate Glasses in Relation to Their Chemical Structure
Published online by Cambridge University Press: 10 February 2011
Abstract
The chemical structure of a series of aluminum substituted sodium trisilicate glasses is determined by x-ray photoelectron spectroscopy. It reveals a significant change of the chemical structure around the sodium cations and oxygen anions with the addition of aluminum. A microscopic model is developed to understand the composition dependence of the dielectric constant of these glasses in terms of the changes of chemical structure.
