采用聚合络合法制备了高质量的(K0.5Bi0.5)TiO3(KBT)粉末。聚合络合法制备KBT粉末工艺简单，成分均匀度好，烧结性好。以KBT粉末为原料，采用常规的烧结工艺即可成功制备出相对密度大于90%的KBT陶瓷。与固相反应法制备的KBT陶瓷相比，聚合络合法制备的KBT陶瓷具有更好的介电性能和压电性能。讨论了原料粉对KBT陶瓷微观结构和介电性能的影响，并与传统固相反应法制备的粉末进行了比较。
High quality (K0.5Bi0.5)TiO3 (KBT) powder has been successfully prepared by a polymerized complex method. The polymerized complex method is a simple process used to produce KBT powder with good compositional homogeneity and sinterability. KBT ceramics with a relative density of more than 90% can be successfully fabricated from the KBT powder even by a conventional sintering process. The KBT ceramics produced by the polymerized complex method show better dielectric and piezoelectric characteristics than the KBT ceramics prepared by a solid-state reaction method. The effect of the starting powder on the microstructure and dielectric properties of the KBT ceramics is discussed in comparison with the case of the conventional powder synthesized by the solid-state reaction method.
