摘要：

A systematic study of BaSnxTi1-xO3 solid solutions (x=0-0.20) by a combined field-induced dielectric and ferroelectric analysis with Raman and PFM investigations was realized, in order to obtain new insights concerning the composition-induced modification of the structural phase transitions and ferroelectric-relaxor crossover induced by the increase of Sn addition. The ceramics prepared via solid state reaction and sintering at 1400 degrees C/4 h showed average tetragonal symmetry for x <= 0.15 and cubic for x=0.20. However, the dielectric and Raman analysis demonstrated that x=0.05 and x=0.15 are characterized by a coexistence of phases, which enhances their macroscopic properties (polarization for x=0.05 and permittivity for x=0.15). The domain structure shows a gradual modification when increasing Sn addition. No detectable domain structure has been found for x >= 0.15. All the compositions show local d(33)(V) hysteresis loops at room temperature. (C) 2014 Elsevier Ltd. All rights reserved.
