摘要：

Effect of sintering atmosphere on the microstructure and electrical properties of the doped BSCT ceramics was investigated. More oxidizing sintering atmosphere weakened the donor-incorporation effect in the sample and improved the density, grain size, resistivity, and dielectric properties. Especially, when the sintering atmosphere changed from air to O(2), the resistivity and maximum of partial derivative epsilon/partial derivative T increased about four orders of magnitude and two times, respectively, while the tan delta at T(C) decreased about 60%. This was very suitable and important for pyroelectric materials working at the DB mode.
