BaSn (x) Ti(1-x) O(3) (short for BTS) ceramics are prepared via the conventional solid state reaction method. The microstructures, diffuse phase transiton, dielectric and ferroelectric properties of BTS ceramics were investigated. These results indicate that Sn(4+) ions have entered the unit cell maintaining the perovskite structure of solid solution. The incorporation of SnO(2) can limit grain growth in the BTS ceramics. The Curie temperature of BTS ceramics decreases with the increasing of tin content. Addition of tin can decrease dielectric loss of BTS ceramics at room temperature. The diffuseness of the phase transition of BTS ceramics enhances with the increasing of tin content. The coercive electric field (E (C)) increases as tin content increases when x is 0.10-0.20. Moreover, the remanent polarization (P (r)) of BTS ceramics decreases with the increasing of tin content.
