Abstract

High-quality SrBi₂Ta₂O₉ single crystals were grown by a self-flux solution method using Bi₂O₃ added with B₂O₃ flux. Chemical composition corresponded to the formula Sr_xBi_yTa₂O₉ where x=1.03±0.05 and y =1.87±0.08. Transparent SBT crystals obtained by slow cooling (2 °C/h) of the melt from 1350 °C to 1100 °C, exhibit platelet morphology with typical sizes of 5×3×0.05 mm³ dimensions with a dominant (001) orientation of a major face. Ferroelectric hysteresis and dielectric properties are measured perpendicularly to the major face of the crystals. Anisotropy, crystalline orientation, growth mechanism, and their influence on electrical properties are discussed.
