摘要：

The phase evolution, microstructure and dielectric properties in the Ca2+ substituted Bi2O3-ZnO-Nb2O5 system were studied. The crystalline phases of the [Bi-1.8(CaxZn1-x)(0.2)]Zn0.6Nb1.4)O-7 pyrochlores (0.0 <= x <= 1.0) depend greatly on the ratio of ionic radius A/B. With the Ca2+ substitution for Zn2+ in the A site, the crystalline phase transformed from cubic to monoclinic and pure monoclinic phase was obtained for x >= 0.5. As the x value increased from 0.5 to 1.0, the permittivity in the microwave range decreased from 76.4 to 75.0, the quality factor Qf value increased from 1800 to 4700 GHz, and the TCF value shifted from -99 to -147 ppm/degrees C.
