Effect of K2O/BaO ratio on crystallization, microstructure and dielectric properties of strontium titanate borosilicate glass ceramics

Abstract

Crystallization. microstructural and dielectric behaviour of glass ceramics in the system [SrO.TiO2]-[2SiO2.B 2O3]-[(1-y)K2O.yBaO] with varying y, have been investigated. K2O to BaO ratio has been found to play an important role in glass forming and crystallization of strontium titanate phase. It has been observed that optimum amounts of K2O and BaO are required for easy glass formation and crystallization of strontium titanate phase. © 2003 Published by Elsevier Ltd. and Techna S.r.l.
