Correlation between electrical conduction and dielectric polarization in inorganic glasses

Abstract

Dielectric polarization, whose activation energy is nearly equal to that of the electrical conduction, has been found in many alkali-silicate glasses and is presumed to be due to the migration of alkali metal ions <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1,2</sup> or some special type of interfacial polarization. <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> However, the mechanism of polarization has not yet been clarified.
