通过常规的氧化物混合方法制备（1-x）BaTiO 3-xK 0.5Bi 0.5TiO 3（缩写为BT-KBT，0.10 μ m × 0.15）电介质陶瓷。研究了KBT含量对BT陶瓷的致密化、显微结构和介电性能的影响。密度表征结果表明，KBT的加入显著降低了BT陶瓷的烧结温度，烧结温度可达1280°C左右。XRD分析结果表明，所有样品的物相组成均为纯的四方相。介电常数和介电损耗随KBT含量的增加先增大后减小。在100 Hz ~ 2 MHz频率范围内，测试了介电常数和介电损耗随频率的变化。结果表明，复合材料的介电常数和介电损耗随KBT含量的增加而呈规律性变化。
(1−x)BaTiO3–xK0.5Bi0.5TiO3(abbreviated as BT–KBT, 0.10≦x≦0.15) dielectric ceramics were prepared by a conventional oxide mixing method. The effects of KBT content on the densification, microstructure and dielectric properties of BT ceramics were investigated. The density characterization results show that the addition of KBT significantly lowered the sintering temperature of BT ceramics to about 1280°C. The XRD results showed that the phase compositions of all samples were pure tetragonal phases. The dielectric constant and dielectric loss firstly increased and then decreased with the increase of KBT. In addition, dielectric constant and dielectric loss versus frequency were characterized in the frequency range from 100Hz to 2MHz. It is found that the dielectric constant and the dielectric loss changed with the increase of KBT contents regularly.
