Abstract

BaTb_0.01Sn_xTi_0.99-xO₃(x=0, 0.05, 0.10, 0.15) ceramics were prepared by conventional solid-state method. The effects of Sn-doping amount on microstructure and dielectric properties of the ceramic were investigated by X-ray diffraction, SEM and impedance analyzer. The results show that single-phase perovskite structure formed and the grain size reduced by doping SnO₂. When the content of Sn was 10 mol% and sintering temperature was 1350℃, the Curie point of BaTb_0.01Sn_0.1Ti_0.89O₃ ceramic shifted to room temperature and the dielectric constant significantly increased. The dielectric constant of BaTb_0.01Sn_0.1Ti_0.89O₃ ceramic reached 9069, and the dielectric loss was only 0.011 at room temperature.
