Abstract
Dielectric properties of glass ceramic samples prepared in the system [(Pb1-xSr x )O.TiO2)]- [2SiO2.B2O3]-[K2O]-[BaO] have been studied. Dielectric constant vs temperature plots of lead rich glass ceramics samples show a peak similar to Curie peak in case of ceramic lead strontium titanate. The Curie temperature of tetragonal crystalline phase of various glass ceramics has been found to decrease with Pb/Sr ratio in the initial glass. This complements X-ray diffraction (XRD) studies carried out previously to establish that the crystallites in various glass ceramic samples are (Pb1−xSr x )TiO3 solid solutions.
