摘要：

Glass ceramics in the 20MO.55Bi(2)O(3).25B(2)O(3) (M = Sr, Ba) system were prepared by conventional melt quenching method, followed by heat treatment XRD patterns show that the crystalline phase boron sillenite (Bi24B2O39) was formed on thermal treatment. The variation in the microstructure of the sample as a function of crystallization temperature was studied using scanning electron microscopy. The structural changes due to heat-treatment of the glasses have been explained on the basis of the changes in FT-IR and FT-Raman spectra. The glass cerarnics in the present study have relatively high dielectric constant and low dielectric loss. (C) 2014 Elsevier B.V. All rights reserved.
