Structural, dielectric, electric, and ferroelectric properties of different routes derived of Ba1-xSrxTiO3 (BSTO) ceramic
Ba1-xSr3TiO3 (BSTO) is a suitable material for microelectronic device applications due to its high response of the dielectric permittivity an applied electric filed. We have investigated crystal structure, dielectric response, electrical conduction and ferroelectric properties of BSTO. Sol gel and solid state processing were used as routes for the synthesis of BSTO ceramics. The microstructures including grain size and phase analysis have been examined using SEM, X-ray diffraction, and Raman Spectroscopy. The chemical characterization was measured by EDS. From the temperature dependence of measured relative permittivity, loss tangent and, tunability at frequencies between 1 KHz to 1 MHz, the ferroelectric phase transition of BSTO-sg (x=0.4) was observed in ~ 238K, BST-ss (x=0.4) in 267K, and BST-sg & BST-ss (x=0.3) were observed both in ~312K.
