Abstract
(Ba0.6Sr0.4) TiO3 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.
