Abstract
AbstractSoda‐lime silicate glasses, with compositions corresponding to the immiscibility range, were studied to characterise their electrical properties and to determine the dependence of these characteristics on the glass microstructure. Dielectric measurements, analysed in terms of Maxwell/Wagner/Sillars theories of inhomogeneous dielectrics, have been used to investigate the phase separation characteristics of soda‐lime silicate glasses exchanged by copper. Such measurements are shown to provide evidences of the continuous or discontinuous nature of separated phases, the presence of which has been confirmed by the transmission electron microscopy observations. The results indicated that dielectric measurements are particularly useful in following phase‐separation‐processes in the oxide glasses. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
