<001> Textured Pb(Mg_1/3Nb_2/3)O₃–PbTiO₃ Ceramics Prepared by Reactive Templated Grain Growth

Abstract:

<001> textured Pb(Mg1/3Nb2/3)O3-0.325PbTiO3 (PMN-32.5PT) ceramics were prepared by reactive templated grain growth (RTGG). Plate-liked {001}-SrTiO3 single crystal particles were used as template seeds. MgNb2O6, TiO2, PbO were mixed with SrTiO3 templates as a reactive matrix. SrTiO3 templates were oriented after tape-casting. The textured PMN–32.5PT ceramics were produced after heat treatment. In preparing textured PMN-32.5PT, RTGG was more efficient than TGG because of the chemical energy released in reaction. The final texture degree was very sensitive to the sintering history. An initial anneal step below the melting point of PbO resulted in better development of texture.
