摘要：

SrBi2Ta1.6Nb0.4O9 (SBTN) and SrBi2Ta2O9 (SBT) ceramics with typical bismuth layered perovskite structure were synthesized by hot-press sintering at 1000 degrees C for 2 h. The maximum relative density of as-sintered SBTN and SBT materials is 98.97%. The domain structure of SBTN and SBT was systemically characterized by means of TEM and HRTEM. The 90 degrees domain walls were identified by the 90 degrees rotation relationship of the electron diffraction pattern along the [0 0 1] zone axis. Irregular shaped and highly curved 180 degrees domain wall were also observed in SBTN ceramics. The traditional alpha-fringes can be found in SBT, which are the evidence of large strains in hot-press sintering ceramics. Rod-like SrTa2O6 precipitates are also analyzed as well as its interface with the matrix. (C) 2012 Elsevier Ltd and Team Group S.r.l. All rights reserved.
