| dc.description.abstract | Barium strontium titanate (Ba<inf>0.8</inf>Sr<inf>0.2</inf>TiO<inf>3</inf>; BST) ceramics, were prepared by the hybrid method between Solid-state reaction (SSR) and Sol-gel methods (SG) in a ratio of 1:0.1–1:0.5. The BST powder was successfully calcined at 850 °C for 2 h. This temperature is much lower than the calcination temperatures of the SSR method. The BST ceramics were sintered between 1150 and 1450 °C. All samples showed the pure perovskite structure corresponding to JCPDS no. 34-0411. The optimum sintering temperature was observed from the samples sintered at 1450 °C for 4 h, indicating a density of 5.26 g/cm<sup>3</sup>, dielectric constant of 7018, and ferroelectric properties: (P <inf>max</inf> = 13.8 μC/cm<sup>2</sup>, P <inf>r</inf> = 2.5 μC/cm<sup>2</sup> and E <inf>c</inf> = 2.3 kV/cm at 30 kV/cm). | |
