The method of two-steps sintering was applied to Ba(Ti0.8 2Sn0.18)O3 ceramics to improve their electrical properties. The ceramics were sintered at T1(1350°C) with a short time, followed by firing at T2 (1100°C) for 4-16 h. Effects of dwell time at T2 on the properties of the ceramics were investigated. The examination of dielectric spectra indicates that the ceramics exhibited a relaxor behavior. An improvement in density and dielectric constant at the transition temperature of the ceramics were observed for a longer dwell time. The dielectric behavior was confirmed by the ferroelectric behavior of the samples. © 2013 Copyright Taylor and Francis Group, LLC.
