ABSTRACT Ferroelectric (Ba, Zr)TiO 3 (BZT) glass‐ceramics doped with varying BaO–B 2 O 3 –SiO 2 glass contents (0–0.15 wt.%) were synthesised via solid‐state reaction. It was found that the introduction of the glass additive significantly reduced the sintering temperature of the pure perovskite BZT phase (1180°C) compared to conventional BZT ceramics, while simultaneously increasing the relative density to over 96%. This phenomenon is primarily attributed to the liquid phase formed by the glass additive at lower temperatures, which enhances particle wetting and inhibits grain boundary migration. Although dielectric constant decreased progressively with increasing glass content, the sample doped with 0.1 wt.% glass retained favourable dielectric characteristics at the paraelectric state. This study demonstrates a viable strategy for optimising key performance parameters low‐temperature sintering, low loss, high breakdown strength and high‐frequency stability exhibiting competitive performance relative to lead‐free ferroelectric ceramics in low‐temperature co‐fired multilayer ceramic capacitors (MLCCs).
