Abstract

Barium stannate titanate [Ba(Sn_xTi_1-x)O₃, x=0.1, 0.2, 0.3, and 0.4] ceramics were prepared using a conventional solid-state reaction process. Their dielectric properties were measured under direct current bias fields ranging from 0 to 2.5 kV/cm. A transformation from normal to relaxor ferroelectrics was observed when x≥0.3. Broken long-range order or "dirty" ferroelectric domains and nanodomains were observed in Ba(Sn_0.1Ti_0.9)O₃ and Ba(Sn _0.4Ti_0.6)O₃ by transmission electron microscopy, respectively. Voltage driven tunability was found to decrease with increasing Sn content. The change from normal ferroelectric into relaxor ferroelectric had a negative impact on the tunability value of the materials. © 2004 American Institute of Physics.
