A XANES investigation of the network-modifier cations environment before and after the Na+/K+ ion-exchange in silicate glasses

μ-XANES is used to study the modifications in the alkali and alkaline-earth environments induced by the Na+/K+ ion-exchange process in various Na –silicate glasses. The results indicate that the ion-exchange process induces a shortening of the NaO, CaO and MgO bond distances. The contraction of the...
