Abstract Full text About this article

Perovskite (Ba,Sr)TiO3 glass ceramics were crystallized in the presence of La2O3 for glass ceramic system [(Ba1-xSrx)TiO3]–[2SiO2–B2O3]–[K2O]–[La2O3] (x = 0.0 and 0.4). The formation of major crystalline phase of BaTiO3 along with secondary phase of Ba2TiSi2O8 was confirmed by X-ray diffraction (XRD) studies. Major crystalline phase was clearly seen in the micrographs of (Ba,Sr)TiO3 borosilicate glass ceramic samples. The prepared glass ceramic samples showed very high values of toughness and elastic modulus. Barium strontium titanate (BST) glass ceramics are used in barrier layer capacitors for storage of high energy due to their very high dielectric constant and low dielectric loss.

Abstract

Perovskite (Ba,Sr)TiO3 glass ceramics were crystallized in the presence of La2O3 for glass ceramic system [(Ba1-xSrx)TiO3]–[2SiO2–B2O3]–[K2O]–[La2O3] (x = 0.0 and 0.4). The formation of major crystalline phase of BaTiO3 along with secondary phase of Ba2TiSi2O8 was confirmed by X-ray diffraction (XRD) studies. Major crystalline phase was clearly seen in the micrographs of (Ba,Sr)TiO3 borosilicate glass ceramic samples. The prepared glass ceramic samples showed very high values of toughness and elastic modulus. Barium strontium titanate (BST) glass ceramics are used in barrier layer capacitors for storage of high energy due to their very high dielectric constant and low dielectric loss.
