Synthesis of Ba1-xSrxTiO3 by Sintering and Sol–gel Methods

Piezoelectric materials, such as PZT and BaTiO3 are used in various applications such as super capacitors, dielectrics, ceramics and catalysts [1, 2]. Barium titanate (BaTiO3) provides many advantages as far as its structural, piezoelectrical and ferroelectrical properties are concerned [3]. However, in order to enhance these properties, barium was substituted with strontium via sintering and sol-gel method. Barium strontium titanate (BST) ferroelectric materials have garnered significant interest because of their chemical stability, large permittivity, high tunability, and minimal dielectric losses [4]. In this study, the synthesis by sintering and sol-gel process of perovskite Ba(1-x)SrxTiO3 (consisting of 0% to 50% Sr) materials is demonstrated. Moreover, all samples were examined via Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), Differential Thermal Analysis (DTA) and Thermogravimetric Analysis (TGA).
