Phase Transition and Electrical Properties of Ba_0.8Sr_0.2TiO₃: Comparison of Different Preparation Techniques

Abstract:

This research studied the effect of the different preparation technique on phase transition and electrical properties of Ba_0.8Sr_0.2TiO₃. The samples compared 3 preparation technique, there are conventional mix-oxide, molten-salt and seed-induced method. The samples prepared by molten-salt calcined at 800 °C, the samples prepared by conventional mix-oxide and seed-induced method was calcined at 1200 °C for 3 h. All of samples sintered at 1400 °C for 3 h. The phase formation and morphology of samples were characterized via X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The dielectric properties of the samples were measurement by LCR-meter.
