AB  - In this work, \((1-x)\text{Ba}_{0.85}\text{Ca}_{0.15}\text{Ti}_{0.9}\text{Zr}_{0.1}\text{O}_{3} - x\text{Sr}_{0.7}\text{Bi}_{0.2}\text{TiO}_{3}\) (BCZT–SBT) ceramics with \( x = 0 \) and \( x = 0.025 \) were prepared through the conventional solid-state route. The samples were calcined at \(1200\,^{\circ}\text{C}\) for \(6\,\text{h}\), then re-milled, pressed into pellets, and sintered at \(1325\,^{\circ}\text{C}\) for \(6\,\text{h}\). XRD patterns indicate the formation of a cubic perovskite structure. A small decrease in lattice parameter is observed upon introducing SBT (\(a\) decreases from \(4.0176\,\text{Å}\) to \(4.0149\,\text{Å}\)), accompanied by a slight reduction in unit-cell volume (\(64.85\,\text{Å}^3\) to \(64.72\,\text{Å}^3\)). \(\varepsilon_r\) increases strongly with \( x = 0.025 \): at \(1\,\text{MHz}\), \(\varepsilon_r\) rises from 1057 (\( x = 0 \)) to 2175 (\( x = 0.025 \)), while \(\tan\delta\) remains low (0.034–0.037). Ferroelectric measurements at \(30\,\text{kV/cm}\) show an increase in maximum polarization from \(11.06\,\mu\text{C/cm}^2\) (\( x = 0 \)) to \(23.5\,\mu\text{C/cm}^2\) (\( x = 0.025 \)), with the coercive field decreasing from \(6.9\,\text{kV/cm}\) to \(5.1\,\text{kV/cm}\).
