Abstract. Ba0.6Sr0.4TiO3 (BST) ceramics were synthesized using the conventional solid-state method and characterized for their dielectric and electrical properties toward multilayer ceramic capacitor (MLCC) applications. X-ray diffraction confirmed a single-phase cubic perovskite structure, indicating successful Sr2+ substitution in the Ba2+ lattice. The dielectric constant (εᵣ) exhibited thermally stable behaviour, decreasing from 2601.69 at 40 °C to 290.72 at 200 °C, while dielectric loss (tan δ) remained low (0.03-0.05) across the temperature range, reflecting minimal energy dissipation. AC conductivity increased with temperature following Jonscher’s power law, suggesting thermally activated charge transport. Impedance analysis revealed a transition from grain-dominated resistivity at low temperature to mixed grain and grain boundary conduction at higher temperatures. The combination of high dielectric stability, low loss, and tunable electrical response demonstrates that Ba0.6Sr0.4TiO3 is a promising candidate for thermally stable and low-loss dielectric components in advanced MLCC applications.
