摘要：

ZnO-B2O3-SiO2 additive with 0.55: 0.35: 0.10 molar ratio was added to Ba0.3Sr0.7TiO3 ceramics in order to lower the sintering temperature. The densification behavior, crystalline structure, microstructure, dielectric properties and breakdown strength of ceramics were studied. When 9 wt.% additive was mixed with pure Ba0.3Sr0.7TiO3 powder, the densification temperature of samples decreased from 1350 degrees C to 1100 degrees C compared with no additive system, and the sintered ceramics revealed dielectric properties at room temperature as follows: dielectric constant epsilon r = 413, dielectric loss tan = 0.00231 under 1kHz and the breakdown strength Eb = 9.2kV/mm.
