Dielectric Loss of Microstructurally Anisotropic Borosilicate Glass

Dhdelectric characteristics were determined for a microstructurally anisotropic borosilicate glass prepared by uniaxiallhd stretching phase‐separated glass rods. The specimen showed a dielectric loss peak caused by the inhomogeneous microstructure; its magnitude varied with the orientation of the specimen with respect to the electric field direction. The results are in agreement with Sillars’ theory. Copyright © 1981, Wiley Blackwell. All rights reserved
