(Ba 0.6 Sr 0.4 ) TiO 3 thick films doped with glass slurry were fabricated by the screen‐printing technique. The dielectric properties and the sintering mechanism were investigated. The films can be sintered at 600°C. The dielectric constant is 88 and the dielectric loss is 0.002 with a tunability of 23.86% under 100 kV/cm. Higher dielectric constant and tunability were obtained in the samples sintered at higher temperatures. The highest tunability is 61.12% under 150 kV/cm in the sample sintered at 800°C. The low sintering temperature and dielectric loss of the glass‐doped thick films make them potential candidates for LTCC and microwave tunable devices.
