High Dielectric

Sr(Bi1-xSmx)8Ti7O27 ceramics were prepared by Sm2O3-substitution for Bi2O3 through solid-state reaction route. The dielectric properties of the sintered bodies such as er, Q and tf were investigated. The ceramics were characterized by SEM, XRD, DTA and TG, which behaved high dielectric constant of 128 ~154 at the frequency of 10 GHz.

Second Phases

The microwave dielectric properties of the Mg(Zr0.05Ti0.95)O3ceramics with CuO addition were investigated. All specimens were prepared by solid-state reaction method and sintered at 1270-1420°C for 4 h. When CuO was added, the second phases of MgTi2O5, TiO2and liquid phase were produced. For specimens with 1.5 wt% CuO sintered at 1300°C, the dielectric constant,Q´fand tfvalues are 18.2, 223000 GHz and -2 ppm/°C, respectively.
